Here are the things I love about it:
1. It is dishwasher safe, really. (I have had others that said they were but then could not handle the heat.)
2. It has a bigger top than most and is easier to push.
3. The top comes off the container so that it can be filled from the top instead of the bottom.
5. By pressing down and turning, it becomes much shorter so that it will fit into more spaces.
Over all it is one of my favorite kitchen gadgets to chop nuts, olives, onions, peppers, etc.
If you are looking for one, this is the best one out there. Happy chopping.
