Review (4/5): Great product - but be careful!
I was really excited to get this trimmer. I had an older model that my son took to college and I was looking a bit scruffy. The first time I set it to "4". I was used pushing down hard to get an even trim with my old one. Well with this new one I pushed so hard that the trimmer length setting was reduced. I didn't realize what was happening until it was all the way down to "1". I wound up shaving it off. I regrew my facial hair and haven't had any problems since. I just don't push as hard and I make sure it is firmly set on the length I want. BTW: the vacuum feature works great.
