Ninja's new Slushi Max is bigger, faster and smarter than ever

Ninja changed the game when it released its Slushi frozen drink maker last year, and ahead of peak hosting season in 2025, the Slushi has had an upgrade. Ninja just released the Slushi Max frozen drink maker, which is designed to turn almost any drink into a frozen beverage faster and smarter than before. Its 150oz capacity can make up to 12 drinks in one go, which is five servings more than the original's 88oz capacity.
The original Slushi is so simple to use, with five one-touch settings that create everything from a milkshake to spiked slush. But Ninja has added an even easier way to get the perfect drink with no effort in its new Slushi Max. Now with SlushAssist Technology (yep, that's what it's called), this machine will customize its own settings depending on the volume and ingredients you're using.
There's some bad news, though. The Slushi Max is an eye-watering $499 at SharkNinja.com, which is more than I like to spend on, well, anything.
Available in three shades: Blue & Pink, Orange & Blue or Lemon & Mint, the Slushi Max has a 150oz capacity that can make up to 12 drinks in one serving, making it ideal for hosting this festive season.
Here's what's new
Because it can brew colder than before, it can handle higher-alcohol drinks.
The Slushi Max claims to solve two of the most common complaints I see people making about the original. Firstly, because it can brew colder than before, it can handle higher-alcohol drinks. That's a big win for hosting season. I've been overcoming this problem by putting the base of my frozen cocktail in the Slushi and simply topping it up with liquor, but this is a much easier way of getting the party started.
Secondly, because it can serve up to 12 people in a single round, the Slushi Max will ensure your guests aren't left wanting more. My Slushi struggled to keep up with demand when I had company this summer, so that's the sort of upgrade I was hoping to see from Ninja's latest version.
The Max has five settings, which is the same as the original, but it also has SlushAssist Technology. What does that mean? According to Ninja, "SlushAssist Technology is your behind-the-scenes expert, sensing your liquid ingredients & auto-adjusting the temperature for perfect results every time."
So, I'd imagine it responds to the resistance your auger is facing from your drink and adjusting the settings to either speed up your chilling time or prevent your drink from becoming too frosty to drink. But I'll need to get hands-on with the Slushi Max to find out for myself.

My biggest pause for thought is just how expensive this machine is. The original Slushi retails for $349, making the Max $150 more expensive. I'd spend $499 on a coffee maker, or (at a push) a very high-quality blender, but this is the definition of a non-essential countertop appliance, which could make the price tag a bit too much to swallow for some people.
