I went to the store to get some razors for my mach 3 whatever, cause i ran out and their expensive as hell. So i saw a pack with the mach 3 power and like a free shave gel bottle for less than a pack of razors so i decided to try it. Am i impressed. You would think they're bullshitting with the smothest shave, butt their not. I haven't had a smoth shave like this in months. The vibrations really help get the smooth shave and the also help prevent from getting nicks and cuts, since it vibrates and helps the razors go smothly over skin. I highly recommend this product.
