Wow. Up until about 3 years ago...every time I peeled potatoes my hands and arms would turn red and itch like crazy. My eyes would swell and also be beet red. If these really work I would have loved to have them!
Luckily now I can peel away with no side effects.

It takes me about 8 seconds or less to use a veggie peeler to peel a potato. This would just be one more thing I need to find room for in my kitchen. Looks like it would be kind of fun to use though (maybe).
Do you think when it starts to get old you wouldn't need parsley in your potatoes cos you'd have blue flecks through them instead? And would it take the 'eyes' out?
What they might be good for is taking the mud off shoes or boots! Then again they'd probably take the leather off as well!
