I've had it for a short time but it works great. It cuts through potatoes of all sizes like a breeze. It doesn't work well with yams or sweet potatoes; you need to cut those down because it's a lot of work to get them through the blades, but if you can deal with short fries it's works just fine with about an inch or an inch and a half of yam or sweet potato. I'd like to try it on squash or cucumbers to see how well it does. I really like it cuz I'm trying to eat healthy and I like to make french fries with the air fryer both regular potato and sweet potato or yam. And this really helps me to accomplish it. The frozen sweet potato fries in the market have too many calories, sugar,, oil and other junk, and it's great to be able to use this machine to eat healthy and make great healthy tasting air cooked fries.
