content: I've been very disappointed with this since we got it. Even with the unit fully charged & operating with the cord plugged in, it struggles to keep up with normal hair cutting. It takes multiple passes to cut, what would have taken our last trimmer, a Norelco plug in model that lasted 8 years, one pass.Build quality: poor. Everything in the kit feels cheap.Too bad we held onto this past the 30 day return policy. Do not buy this trimmer.
