I've had two beard trimmers prior to this one. Both were Babyliss models and both lasted exactly three years (give or take a couple of weeks) - the exact length of warranty!
Disappointed by this plus attracted to the vacuum in this philips model, I decided to purchase it and have been using it for over six months.
I find the turbovac works extremely well - to the point where I can sit at my desk at home, type this review and trim at the same time without any noticeable hair spillage onto the desk! I do however, empty the container more than once (typically 2-3 times, more if I haven't trimmed for a while) and this maintains the vacuum.
When using this trimmer, I found it tells you to trim upwards - ie take the trimmer up your face, not down it, which is what I found the other trimmers tell you to do. It doesn't take long to get used to this and I have quickly adapted to the trimmer.
Holding it was a little awkward at first, given that when you hold it in the natural position, you end up covering the air vents and risk adjusting the comb length. Again, I adjusted rapidly and now hold the trimmer such that my grip is below the air vents.
Because of the upward strokes you make, I have found it a little difficult to trim the moustache, mainly the region under your nose. This is down to design, since with my previous trimmers, I never had this problem. Otherwise, it works nicely.
In fact, it's easy to adjust to using this trimmer and getting decent results. I'm not even put off by the battery and the inability to use from the mains (which the two Babyliss models were able to do).
The one and only thing that does bug me it build quality. I accidentally dropped it onto the floor, fairly near the beginning, when I bought it. I was worried I had broken it but it does fit back together. However, the design means that it is prone to falling, since there's no upright stand and I have dropped it at least four times since. I've managed to put it back together again but please, do be careful with it.
I now regularly take it apart, not because it's broken but because I want to clean it out since hairs do get trapped in and around the system. I find that a can of compressed air (with a straw nozzle) works wonders!

Still going strong after three years of abuse. The motor hasn't stopped, the vacuum function still works and it still holds its charge. No problem with blunt blades.
