In the Iceman Slush-Ease MAX vs Ninja Slushi matchup, the Iceman by Chefman fills to the same 64-oz maximum as the Ninja for about $120 less on Amazon ($179.92 vs $299.00 on Oct 16, 2026). It turned two cans of juice into slush in about 20 minutes for Lilmar, a YouTube reviewer who bought one from Best Buy (Lilmar, “Review of the Iceman Slush-Ease MAX! (Slushee Maker!!)”).
The Ninja has more published testing behind it. Bob Diff, a YouTube reviewer who paid $300 for his unit and tested it with a family of nine, timed batches at roughly 15 to 38 minutes depending on the drink and about 45 minutes at full capacity (Bob Diff, “Ninja Slushi Review – Is This Slushy Machine Worthy of the Viral Hype?”). Here is how the two compare on presets, speed, capacity, cleaning and value.

Iceman vs Ninja Slushi Speed
Lilmar started a batch at 6:25 and had slush by about 6:46, though it was mostly liquid with ice specks for the first 15 minutes (Lilmar, “Review of the Iceman Slush-Ease MAX! (Slushee Maker!!)”). Laura Gaffney, a YouTube reviewer, said hers takes about 30 minutes of mixing (Laura Gaffney, “Iceman by Chefman Slush-Ease MAX Review”), and Rugglestone Reviews, a product-review channel, filled it to the 64-oz line with Coke and had thick slush in about 35 minutes, when the machine beeped (Rugglestone Reviews, “Iceman by Chefman Slush-Ease MAX Review”).
Bob Diff’s Ninja times varied by recipe: a lukewarm caramel frappe took about 15 minutes, a small batch of apple cider slush about 25, frozen mango juice 23 and a chocolate milkshake 38 (Bob Diff, “Ninja Slushi Review – Is This Slushy Machine Worthy of the Viral Hype?”).
| Drink | Machine | Time | Reviewer |
|---|---|---|---|
| Arizona juice slush (2 cans) | Iceman | About 20 min | Lilmar |
| Coke slush, 64 oz | Iceman | About 35 min | Rugglestone Reviews |
| Caramel frappe | Ninja | About 15 min | Bob Diff |
| Frozen mango juice | Ninja | 23 min | Bob Diff |

Presets and Controls
The Iceman has picture buttons for slushy, juice, shake, frappe and cocktail, a favorites button that remembers your setting, defrost and clean buttons and an alert that says when a drink needs more sugar, Lilmar showed. He found his first batch froze too hard because he had set the thickness too high; two or three was enough, and the defrost button loosened it (Lilmar, “Review of the Iceman Slush-Ease MAX! (Slushee Maker!!)”). A “ready” indicator comes on when it reaches the set thickness.
The Ninja pairs five presets with a temperature dial. Bob Diff poured drinks back in and lowered the temperature when root beer came out too liquid, and switched a frozen juice batch to the slush setting for a better texture (Bob Diff, “Ninja Slushi Review – Is This Slushy Machine Worthy of the Viral Hype?”).
Capacity: Which Slushie Machine Serves More?
Both top out at 64 oz per batch. Bob Diff called that about four or five decent-size drinks and said his family of nine has to run it twice. Ninja has since released an 88-oz vessel, sold separately, that also adds an anti-drip spout (Bob Diff, “Ninja Slushi Review – Is This Slushy Machine Worthy of the Viral Hype?”). Chefman lists the Iceman’s 64-oz max fill as serving eight. Lilmar judged it plenty for one to four people (Lilmar, “Review of the Iceman Slush-Ease MAX! (Slushee Maker!!)”).
What You Can Put in Each Machine
- Sugar is required. Rugglestone Reviews warned against diet or sugar-free drinks and plain water for slushing in the Iceman, and added about a third of a cup of sugar to Coke (Rugglestone Reviews, “Iceman by Chefman Slush-Ease MAX Review”). The Iceman’s add-sugar alert flags thin mixes.
- Start cold. Bob Diff said Ninja’s directions say not to add hot ingredients, and suggested chilling mixes first (Bob Diff, “Ninja Slushi Review – Is This Slushy Machine Worthy of the Viral Hype?”).
- Bottled drinks work. Both reviewers made slush straight from soda or juice; Bob Diff called that the machine’s best trait.
Cleaning the Iceman and Ninja Slushi
The Iceman has a clean program: add water, run it, then drain. The manual says to remove and wash the tank and drip tray after every use, Lilmar noted, and both pull off by flipping a lever (Lilmar, “Review of the Iceman Slush-Ease MAX! (Slushee Maker!!)”). The Ninja’s rinse cycle stops chilling and flushes hot water through, but Bob Diff still removes the parts and wipes the evaporator with a damp cloth (Bob Diff, “Ninja Slushi Review – Is This Slushy Machine Worthy of the Viral Hype?”).
