The very first time I used it, it worked great. After that, it was a huge hassle. I used it mainly to chop onions and garlic because chopping those things by hand is quite a teary eyed situation. It seemed as if after using it once, the blades instantly dulled. I tried to chop an onion, and instead it smashed it. After who knows how many slaps, I finally gave up and put it away for a while. When I brought it out again, I guess I had the hope that somehow it had managed to sharpen itself in the cupboard, because I tried it again. This time I got so frustrated that it wasn't doing anything but smashing my onions, that I guess I slapped it too hard and I cracked my cutting board. Grumbling, I threw my cutting board away and half a second later, the Slap Chop joined my poor, abused cutting board in the trash can. Never again will I have anything else even remotely like this! Ease of Cleaning It wasn't easy to clean at all! The only time it wanted to act sharp was when I was trying to clean it.
