Review (4/5): A good replacement
This is my second trimmer. My first, a Remington was at least 15 years old and worked like a champ. It had it's problems like many of these in holding the desired length. But you learn to hold it tight so it won't change while trimming. I babied the batteries for years and quite honestly if you don't, with Ni-Cads you'll be replacing them or the trimmer a lot sooner.
I like this one and was concerned by some of the negative reviews. I don't use a lot of pressure when trimming so I haven't seen it change (shorten) while trimming. The vacuum feature is nice and works well. Others complained about getting up under the nose. This is no different from any others I've tried that use a blade guard.
I'd give it 5 stars if I had it longer. So far so good and has lived up to or beyond my expectations. I'm still on the first charge so time will tell. If it lasts half as long as my Remington I'll be happy.
