I've hand-selected the 9 best Prime Day Ninja deals — save on the Creami, air fryers and more

One of Ninja's cheaper products, the Blast portable blender is impressively powerful. Sure, it can't compete with a full-size blender, but it did a great job of handling everything from protein powder to frozen berries when I put it to the test.

This genius waffle maker is super popular on TikTok thanks to its top-pour design that prevents it from overflowing all over your countertops. For $79, it's an awesome investment to get you through the colder months.

The Ninja Air Fryer Pro 4-in-1 is my top-rated air fryer for most people. It's a great compact air fryer that's got plenty of power, and I enjoy that despite its limited 5-quart capacity, it can cook up enough fries or wings for a whole family. And because of the 400°F top temperature, it's going to give you a delicious, crispy texture.

Save a massive 42% with this blender food processor combo. The Blender & Food Processor Combo has a 64 oz. max liquid capacity, and its 1500-watt motor is incredibly powerful. I tested the blender-only version of this combo, but I was a big fan, so this expanded edition with attachments for chopping and single-serve blending is bound to be even better.

The Ninja Crispi is one of Ninja's most interesting recent releases. It features a removable cooking lid and interchangeable glass containers to cook meals of a range of sizes. And while I had my doubts, it blew me away in my Ninja Crispi review. In the end, I gave it a well-deserved 4.5 stars.

Ninja reinvented the air fryer game with its DualZone models, and the DZ201 is the largest of the bunch. With two 5-quart baskets, it can double up to make french fries for the whole family, or cook your main and your side simultaneously.

The Creami is famous for a reason. I use it all the time to turn everything from frozen yoghurt to homemade custard into tasty gelato. And if you're keen on increasing your protein goals, you can also freeze a shake and turn it into tasty, low-cal ice cream.

The Ninja DoubleStack Air Fryer is one of Ninja's most innovative releases. This two-drawer air fryer saves a huge amount of counter space by stacking one drawer on top of another, doubling its cooking capacity for its footprint. It's got two drawers of 4-quart capacity, and comes with roasting trays to stack foods inside the drawers, too.

One of Ninja's best value options is this 14-piece knife set, and that's before this 36% discount. The set includes an in-built sharpener and even six steak knives. I've tried some market-leading knives in my years of testing, and this set from Ninja outperforms a lot of them.
