I've been wanting to try a foil shaver as an occasional alternative to a blade, so following the good advice here I picked up an Andis Profoil Lithium. Just tried it and I'm very impressed with the tight, smooth result, almost blade close.
I did notice some friction between shaver and my dry head, causing some minor tugging and skipping of the shaver. Should I be using a product like Williams Lectric Shave for a pre-shave conditioner? This is all new territory for me so what do you recommend as a skin treatment for foil shaving?
