Love this fry pan. Had first Ninja for 5 years, time to replace.

Be careful. These blades are sharper than razor blades. A friend grabbed the blade assembly to wash it not realizing they were so very sharp. He cut himself. - badly. Not deep enough for stitches but close to it. So use caution.

The machine works very well and I would imagine with the blades being so very sharp they will stay so unless one grinds up nails or ice cubes. This is my second Ninja and I love the brand. My first Ninja lasted for years but someone dropped the plastic "pitcher" and it cracked. To buy a replacement the cheapest I could find on ebay was about $45.00. This model was on sale and was an improved version with lots of attachments. So decided to buy it. The quality of the Ninja is almost always very good. It blends fresh herbs very well and liquids are a snap. I have yet to try blending/grinding something hard like peanuts or pepper corns. No regrets other than the bandages on my friends finger. As a precaution, I have since wrapped the blades in paper towels to avoid another mishap.

I've been using this for months and find myself disappointed in the features. Its toaster-oven features are less than optimal. Even at a dark setting, the toast is only a light brown and only toasted on one side!! You need a special tool to pull out the food tray without burning your fingers since the tray doesn't pull out automatically when you flip open the door. No manual was included so who knows what features there are that aren't intuitive. And theres nothing to stop air fryer drips from burning the heating element. Not at all what I expected from a Ninja product which are usually well designed. Surely there are better multi-function toaster ovens.
