Review on 9 7 Silver Keyboard Backlight: Effortlessly Detachable & Automatic by Raji Bentz

We needed a detachable keyboard, so we went for this one. It performed well - it's comfortable, detaches easily, folds well, holds a charge well, and basically did what we'd expect from a keyboard. Although initially a few keys unfortunately didn't respond clearly, now, after about six to seven months, there are several keys where the letters have worn away from repeated use and no longer work. I can't find any warranty contact information so I'm hoping the manufacturer/seller will read this and get back to me. Revain has a one year warranty.
