Query: Doesn't shave close, is flimsy and poorly designed, and overpriced.

It just plain doesn't work. It leaves stubble, not a smooth back. Plus it's flimsy so it doesn't stay in position, and is awkwardly designed. It seems like a good product, but it doesn't work right. The company does a good job of getting fake purchasers to spread buzz and positive reviews -- but it's just hype and clever marketing. It *might* work for a few people with a very certain hair type, very flat backs, or something...but I've tried it a few times and am very disappointed with this shaver. Don't buy it.My recommended alternative is Veet for Sensitive Skin if you want to go smooth, or just an adjustable-length beard or hair clipper to trim. Or you know...a girlfriend who's seen your hairy back but loves you anyway. Unfortunately they don't sell those on Amazon.
