Review title is Good idea, poor manufacturing... review criteria needs a review... [SEP] So has no battery meaning whomever set the criteria has no clue what it is making any review kinda useless Ya think?? Not easy to use because the collar used to "snug" the shaft from twisting works once really so cheaply made. Ergonomic handle with adjustable/bendable section allowing you to curve it to get the most of the business end of the razor strapped in by an elastic strap with a velcro strip. Once "adjusted", collar snug sleeve tightened, not a bad result but you'll have to work at it!
