When we bought this, I expected it to be a cheap plastic sealer that would end up in the garbage can in a few weeks... In reality it actually works, and works quite well! The trick is to make sure you smooth out the surface you want to seal. If you do that, the device will seal salt crackers, Cheese crackers, etc., fairly much anything with a plastic or wax bag. The sealed items stay crisp, as if still new. I am very surprised at the build quality as well... I am quite happy with this device.
