Fries are uniform, but takes a lot of pressure to cut them.

I really wanted this product to work better than it did because I liked the idea of making fries at home from home grown potatoes. But it turned out to take a bit more work than seemed necessary for this kind of tool. The plastic used for this product isn't particularly durable. I was afraid to break it because of the pressure I needed to apply to the lid to get the potato through the blades. The first time I tried this with a whole potato and it got stuck a few inches in. So I cut that piece off and tried again with a flat edge (and less potato). I was only able to get it all the way cut with some fist pounding on the lid. I'm not sure if it's that the blades aren't sharp enough or if there was too much potato for it to handle at once. I tried with a quarter of an apple with better results, though it did have a tough time getting through the skin sometimes. I think the trick is to not try to cut too much at once and use softer fruits and vegetables. Unfortunately, that means pre-cutting your potatoes for fries. The fries however, did end up being uniform at 1/4" square and fried up nicely. While the product worked, it couldn't cut a whole potato and the small blade footprint means you'll need to pre-cut anything that goes through this, so it's not really a time saver. The only benefit you'll get from this is evenly cut fries that will take the same amount of time to cook through. Amazon Affiliate Product Link: http://amzn.to/1CNZEU5
