Updated August 2026: Cuisinart marks the ICE-70 discontinued, selling only spare parts for it; SharkNinja’s current lineup has replaced the CREAMi NC301 with the NC351PU and the Deluxe NC501 with the NC601, both at new prices. Every price re-verified against the maker’s own storefront, cost-per-quart recalculated to include the parts each warranty excludes as wear items, and a genuine conflict between two independent labs over the Whynter’s churn time is reported rather than resolved.
The Cuisinart ICE-21 makes a quart of ice cream for 97 cents. The Whynter ICM-201SB makes the same quart for $4.31. Both figures are the machine itself, spread across three years of making two quarts a month, and the ingredients are identical either way.
That is the whole decision, and the $240 in the middle of it buys exactly one thing: not having to plan a day ahead. The Ninja CREAMi is the loser here on every axis except speed, and even that comes after a 24-hour freeze.
What does a quart actually cost on each of these machines?
Seventy-two quarts over three years, which is two a month. The right-hand column adds the parts each maker’s warranty specifically refuses to cover, because those are the parts you buy twice.
| Machine | Price, from the maker’s own store | Machine only, per quart | Parts the warranty excludes | Per quart with those parts |
|---|---|---|---|---|
| Cuisinart ICE-21 | $69.95 | $0.97 | Replacement freezer bowl, $37.95 on Cuisinart’s own parts listing | $1.50 |
| Cuisinart ICE-70P1 (2 qt) | $189.95 | $2.64 | not separately priced for this model | — |
| Ninja CREAMi NC351PU (7-in-1) | $199.99 | $2.78 | Pint containers, 4-pack, $29.99 | $3.19 |
| Ninja CREAMi NC601 (Deluxe, 11-in-1) | $249.99 | $3.47 | Deluxe tub, single, $16.99 | $3.71 |
| Ninja CREAMi Swirl NC701 | $299.99 | $4.17 | Pint containers, 4-pack, $29.99 | $4.58 |
| Whynter ICM-201SB | $309.99 on sale, $339.99 list | $4.31 | none published | $4.31 |
The arithmetic is all division by 72. $69.95 gives $0.9715. Add the $37.95 bowl and $107.90 gives $1.4986. $199.99 gives $2.7776, and $229.98 with the pints gives $3.1942. $309.99 gives $4.3054. Run it on your own frequency and every one of these numbers moves.
Two honest gaps in that table. The $37.95 freezer bowl is the price Cuisinart lists on its ICE-70 spare-parts page; I could not confirm a separate published price for the ICE-21’s bowl, so that row assumes the two cost the same, which they may not. And Whynter’s own storefront wants $309.99 while Home Depot has been listing the same model at $259.99, which would drop it to $3.61 a quart. The spread between retailers on this one machine is wider than the entire price of a Cuisinart.
Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
Which parts will you be buying again, and which ones does the warranty refuse?
Warranty length is the number every listing prints. What the warranty covers is in a separate document, and on one of these machines the two barely overlap.
| What the listing says | What the actual terms say | Verdict |
|---|---|---|
| Ninja: 1-Year Limited Warranty | SharkNinja’s warranty document excludes normal wear on “containers, lids, paddles, and motor bases,” is non-transferable, and charges the owner a $19.95 to $20.95 return-shipping fee on a covered repair | It is a year on the motor, not on the parts owners report breaking, and it is not free. |
| Ninja, implied: keep it a year and you are covered | The same document lists as a void condition “failure to keep the well of the motor base clear of food spills and other debris” | A housekeeping clause. Read it before you call support about a CREAMi that has had ice cream spilled in it. |
| Cuisinart: 3-year limited warranty | Covers defects in materials and workmanship under normal home use. Excludes normal wear and tear, commercial use, and labor and installation costs. Silent on the freezer bowl and silent on transferability. | Three years is real and it is triple Ninja’s. What it does for the one component that wears out is unstated in Cuisinart’s own posted terms. |
| Whynter: 1 year, parts and labor | Original owner only, non-transferable, limited to the 48 contiguous states, freight and insurance excluded | Alaska, Hawaii and anyone buying secondhand are outside it entirely. |
| Ninja: “1 pint” capacity | Ninja’s owner guides say only “DO NOT fill containers past the MAX FILL lines” and publish no ounce figure for the 16 oz pint or the 24 oz Deluxe tub | The usable volume of a CREAMi container is a moulded line, not a number the maker will put in writing. |
| Roundups still recommending the NC301 and NC501 | Neither appears as a standalone product on SharkNinja’s current ice cream maker page. The 7-in-1 slot is NC351PU at $199.99, the Deluxe slot is NC601 at $249.99. Both old pages resolve, out of stock. | A live price on a dead model number. Check the maker’s category page, not the product page. |
| Anyone quoting $189.95 for a “Cuisinart ICE-70” | Cuisinart marks the ICE-70 Discontinued and out of stock, selling only a lid, a paddle and a freezer bowl for it. The live 2-quart machine is the ICE-70P1. | The price is real. It belongs to a different SKU. |
Owner reports line up with that first row uncomfortably well. On the CREAMi Deluxe listing at Home Depot, 6 of the 30 reviews rendered on the page I read described a hardware failure: a pint bowl cracked on first use, stripped mixer threads, a paddle that came off the drive shaft after two years, a unit overheating under the blade inside a year, and an outer lid broken within two weeks. On the equivalent Lowe’s listing, 6 of the 20 reviews on that page said much the same, including one owner on their fifth machine in three years. On a Sam’s Club page, none of the 10 reviews mentioned a failure.
Those are page samples, not the full review counts, and I am labelling them that way on purpose. The Home Depot listing carries 320 reviews in total and the Lowe’s listing 318; I read the ones the page served, not all 638. For the Cuisinart ICE-21 and the Whynter I could not get a comparable sample at all — both listings return an aggregate rating, 4.8 stars across 3,683 reviews and 4.5 across 86 respectively, but the review text itself would not load. So there is no owner-reported failure count for those two machines in this piece, and inventing one would be worse than saying so.
Two labs timed the same Whynter and came back 34 minutes apart
America’s Test Kitchen, in a review updated 11 June 2026, put the Whynter ICM-201SB at an average of about 26 minutes and called the output supersmooth, rating the machine Excellent. Reviewed, updated April 2025, reported the same model taking over an hour, its paddles failing during mix-in additions, and a berry frozen yogurt still too thin after 90 minutes.
Same machine. Two named, dated, professional outfits. A factor of three between them. Neither one is dismissible and I am not going to pick the flattering number for you.
The other two machines drew no such disagreement. ATK measured the ICE-21 at about 17 minutes, rated it Excellent and described the results as even-textured and velvety. It measured the CREAMi’s process cycle at about 1 minute 40 seconds and rated the machine Mixed: raspberry sorbet came out well, vanilla ice cream came out soft and liquidy on a conventional recipe. That last point matters more than it sounds. The CREAMi wants recipes written for the CREAMi.
How much electricity does any of this use? Under a dollar in three years.
Worth computing once so nobody has to worry about it again. Whynter’s compressor draws 180 watts. Seventy-two quarts at 2.1 quarts a batch is about 34 batches, and at 26 minutes each that is roughly 3.1 kilowatt-hours over three years. At the 18.34 cents per kilowatt-hour the Energy Information Administration reported as the June 2026 US residential average, that is 57 cents.
The CREAMi draws 800 watts but runs for about two minutes. Seventy-two quarts means 144 pints, or roughly 4.8 kilowatt-hours, or 88 cents. Both machines cost less to run for three years than one pint of the ice cream they make. Ignore the wattage. The cost here is the box and the plastic.
The tally: wait, price per quart, texture, warranty, bulk
Three machines, five axes, weights I chose and will defend in a sentence each. Scores out of 10.
| Axis (weight, and why) | Cuisinart ICE-21 | Ninja CREAMi NC351PU | Whynter ICM-201SB |
|---|---|---|---|
| Time from deciding to eating, 25%. This is what decides whether a machine gets used or shelved. | 4 — the bowl has to be frozen solid first, and Cuisinart publishes no pre-freeze time at all on the product page. Then about 17 minutes. | 3 — 24 hours to freeze a pint, per Ninja’s owner guide, then 1 to 2.5 minutes | 9 — no pre-freeze of any kind; 26 minutes by ATK, over an hour by Reviewed |
| Cost per quart with warranty-excluded parts, 25%. The figure you pay, not the figure on the shelf. | 10 — $1.50 | 4 — $3.19 | 3 — $4.31, or $3.61 at Home Depot’s price |
| Texture in independent testing, 20%. The reason to make it at home instead of buying it. | 9 — ATK Excellent, even-textured and velvety | 4 — ATK Mixed; sorbet good, conventional vanilla soft and liquidy | 7 — ATK Excellent and supersmooth, marked down for Reviewed’s thin results and paddle failures |
| Warranty on the part that breaks, 15%. Length is easy; coverage is the question. | 5 — three years, but silent on the bowl | 2 — one year, non-transferable, containers and paddles excluded, $19.95 return shipping, housekeeping void clause | 3 — one year, non-transferable, 48 states, freight excluded |
| Bulk and storage, 15%. Every one of these has to live somewhere. | 8 — 7.4 lbs, but the bowl claims freezer space permanently | 6 — 15.9 lbs, plus two or more pints frozen at all times | 3 — 24 to 28 lbs depending on which spec sheet you read; it wants a permanent counter |
| Weighted tally | 7.3 | 3.8 | 5.3 |
The Cuisinart’s 7.3 is 1.00 from wait, 2.50 from price, 1.80 from texture, 0.75 from warranty and 1.20 from bulk. Nothing in that spread is close.
Now move one weight. Push the wait to 45 percent and drop the price to 15, which is exactly how someone who already knows they will not plan ahead should score this, and the Whynter takes it, 6.5 to 6.4. The CREAMi goes to 3.6 and stays last on every weighting I tried. That is the useful result: the argument here is between the cheapest machine and the fastest one, and the CREAMi is not in it.
Every timing above belongs to the lab that ran it, named in the sentence. No machine here passed through our kitchen. Our editorial standards set out how that works.
Cuisinart ICE-21: the cheapest quart, on the longest wait
Seventy dollars, 1.5 quarts a batch, three-year warranty, 7.4 pounds. ATK has named it the canister-style machine to beat for years, and the design is why: there is almost nothing in it to fail. A motor turns a paddle inside a bowl full of frozen coolant.
The bowl is also the catch, twice over. It has to be frozen solid, and Cuisinart’s own product page will tell you the churn takes 20 minutes or less while saying nothing whatsoever about how long the freezing takes. That is a strange thing to leave off a spec sheet for a machine whose entire workflow depends on it. The practical answer is that the bowl lives in your freezer permanently, which costs you the space of a large mixing bowl for as long as you own it.
Second catch: one bowl, one batch a day. The bowl thaws while it churns.
Skip the ICE-21 if your freezer is already full, or if the reason you want an ice cream maker is that somebody asked for ice cream this evening.
Ninja CREAMi: is it an ice cream maker or a frozen-block processor?
The second one, and that is not a criticism so much as a category correction. The CREAMi does not churn a liquid while freezing it. It shaves and re-blends a block you froze yesterday, which is why it can turn a protein shake, cottage cheese or skim milk into something scoopable — bases a churner would render into ice chips.
That is a real capability and nothing else in this comparison has it. It is also the entire case for the machine, because on price, texture with conventional recipes, warranty coverage and owner-reported durability it finishes last.
Buy the current model numbers if you buy at all. NC351PU is the $199.99 7-in-1 and NC601 is the $249.99 Deluxe; the NC301 and NC501 that most roundups still name are out of stock on SharkNinja’s own store and gone from its category page. The Swirl NC701 at $299.99 adds a soft-serve dispenser and is the only one of the older numbers still current.
Skip the CREAMi if you want conventional custard-base ice cream, or if the household is not already in the habit of prepping food a day ahead. It is a meal-prep appliance that makes dessert.
Whynter ICM-201SB: what does no planning cost?
About $240 over a Cuisinart, and 20-odd pounds of permanent counter space. The Whynter carries its own compressor, so there is no bowl to freeze and no pint to plan. Pour in a chilled base, come back, then start another batch immediately if you want one.
Whether it does that in 26 minutes or 90 is the open question above, and it is a real one, because the fast figure is most of the argument for the machine. The other thing worth knowing before you spend: the warranty is one year, does not transfer, and does not apply outside the 48 contiguous states.
Skip the Whynter if ice cream is a two-or-three-times-a-summer event. At that rate the compressor is paying for a convenience you use six times.
Is any of this recalled?
No. A search of the Consumer Product Safety Commission’s recall database returns no recall on any ice cream maker from SharkNinja, Cuisinart or Conair, or Whynter.
Two adjacent recalls exist on these same corporate names and neither touches these machines. Consumer Reports covered SharkNinja’s May 2025 recall of about 1,846,400 Ninja Foodi pressure cookers over a lid that could open under pressure, with 106 reported burns. And CPSC expanded a recall of Cuisinart grill brushes on 27 August 2026 to more than 3.6 million units over metal bristles coming loose. Different products, different factories. They are here because you would want to know I looked.
Where the tally and my own money disagree
The tally says Cuisinart ICE-21 at 7.3. Re-weighted for someone who values not planning, it says Whynter at 6.5 against 6.4, which is a real tie and the only honest place to break one here.
I would still buy the ICE-21, and the reason is the disagreement in the section above. The Whynter’s case rests on speed. One of the two independent labs that timed it says it is fast and one says it took over an hour and the paddles failed. Spending $240 extra on a convenience that two professional kitchens cannot agree exists is a bet, not a purchase.
Buy the $70 Cuisinart. Keep the bowl in the freezer so the wait is already spent. If you make enough ice cream to outgrow it, you will have learned exactly which constraint annoys you, and you will be spending the upgrade money on evidence instead of a guess.
One more thing to check before you order
Open the maker’s own category page, not the product page, and confirm the model number you are about to buy is still on it. Two of the six machines here failed that check, and both still have live pages with live prices.
Elsewhere in the frozen-and-cold department, we asked which nugget ice maker’s output claim survives an independent lab, ran the five-year numbers on a $320 rice cooker against two cheaper ones, and measured blender smoothness per dollar and per decibel. The rest is in Kitchen & Cooking.
