I am very pleased with this potato chipper. It comes with three cutting frames in varying sizes. The cutters are extremely sharp so watch out when changing or washing them.
A good, solid construction with a good suction pad to keep the cutter steady and the cutting frames are really easy to change.
The only down side is it limits the size of the potatoes than can be chipped, but apparently that is the same with most of these cutters. If the potato is really large, I cut it in half, which still makes decent sized chips.
Overall, I would recommend this cutter.
