Now used everyday! The OXO Good Grips Chopper has been such a boost to my kitchen. It's easy to use in a few ways:
1. The grip on the base and plunger handle make for safe chopping without slipping in your hand or work surface. This feature is especially useful for people with hand mobility issues.
2. Very easy to clean. Arrows and instructions are included on all the removable parts, plus everything is simple to remove and reassemble. 
3. Plunger handle can be pushed down into the body and locked for storage. This is great for cupboards with less height.
4. It's compact size means It's great for fiddly chopping and meals for one.
Verdict.
A well thoughtout and designed kitchen tool, that is an excellent addition to the OXO brand.
