These are definitely not leather so sellers please update the description. Hypoallergenic & Painless, Safety DRY & WET Shaver, USB Rechargeable and Portable, It has a Waterproof Design makes it safe to use even in bath or shower. Pros:- Build Quality- Sound Quality- Fast Bluetooth Pairing- Upscale Packaging- Included Accessories (wired cable, carrying bag)- Very Well Constructed- Very SoftCons- Multi Function button takes a little getting used to- Just a little small for over the ear (for adults) but still very comfortableWhen these came in the mail I opened them and was blown away by the upscale packaging. The adhesive backing is *only* there to hold the hook in place long enough for you to secure it to the desk or shelf with the included screws. I have not had a chance to do any charging "speed tests" but when i get the chance ill update my review. I read the reviews for sturdiness, as I understand by adding length, you can get bowing & bend with alot of weight the longer the extensions. No problem there either. The thong shredded the skin between and under my left toes and left blisters across the tops of both feet after about two hours of setting up the camp site. This faja is AMAZING! Save your money and buy the real thing from a company that sells the real thing.
