Mixed feelings on this unit. I wanted to try the Braun 'cause their batteries have a history of lasting longer than most...I think that would be the case with this model. It's well made, runs very quiet, & charges fast. But there's a few things I didn't like. I don't like the selector wheel, it's low profile makes it hard to turn...a thumb wheel is better. The power button is hard to push, wish it was a slider. The trimmer comb clogs up with longer hair too easily. The constant changing of the combs is a pain, one comb that did it all would be better. When you set it down, it rolls to the side instead of laying flat. And you'd think the thinner handle on the bottom would be better, but it makes it harder to hold onto while trimming, easier to drop. So, mixed feelings...still deciding if I'll return it (got a great price).
