Bests & Worsts Reviews from Amazon

Ordered it last week, used it tonight for the first time. Chopped the carrots very well and arm workout was a bonus. However I then chopped some onion and when I tried to open it to take chopped onion out, the top layer of the lid came off. Bottom layer of lid stuck solid into container. I broke two nails and bent a knife trying to open the thing but couldn't no matter hard I tried. Ended up tossing whole thing in trash, onion still inside.
