Rank #1 in Best Slush Machine 2026: 10 Ranked, and Why 2.5L Pours 1.9L
Ninja SLUSHi Frozen Drinks Maker, Blue & Grey (FS301UK)
Price and rating as shown on Amazon when we collected them. Both change.
At number one in this guide is the Ninja SLUSHi FS301UK, a countertop frozen drinks maker with five presets, a WhisperChill compressor and a vessel the listing headlines as 2.5L. It is listed at £299.00, rated 4.5 out of 5 from 450 ratings, and it is the cheaper of the two 1.9-litre Ninja SLUSHi models in this guide — the other sits at £309.99.
The number worth reading twice is printed on the machine's own bullet. The line that says "a 2.5L* vessel" carries the asterisk: *1.9L max liquid fill capacity. That is 76% of the headline figure, and it is the same gap this guide finds on every listing that publishes both numbers — the 3.7L Ninja XL works out at 2,840ml at max fill, and the machine sold as 2.0L takes 1.4L. Buyers comparing the £299.00 model with the £309.99 one are comparing two machines with the same 1.9L fill and the same 11kg weight.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I was really worried this gadget might be one of those expensive gadgets that end up collecting dust, but happily that is definitely not the case!! I have already made frappe, fruit juice slushies, frozen cocktails and the most delicious strawberry milkshake!!So far it seems robust and it's very easy to clean. It's quite a large machine and doesn't fit under my kitchen wall cupboards but I found a corner where it fits. It's quite expensive but in this heat it has been worth every penny! I don't regret this purchase at all, five shiny stars!! 😊⭐️”
Verified purchase“We've used this all summer! Extremely happy with it! Only wish we'd bought the double one!”
