I really like the Buff Wand, was a little skeptical at first, but after a few weeks of using, I'm really impressed. My nails are thin and weak and I would be reaching for the Emery board two, three times a day to smooth out little nicks. (Those annoying little nicks that catch on my clothing). Since using Buff Wand it is way less often. Hopefully my nails will become more resilient in time.
