Review (4/5): Good blend of power and convenience
I bought this mainly to use on my beard, which grows quickly. Overall, I like it. It's not the best (most powerful) trimmer I've ever had, but its other features make up for what it lacks in power.
The adjustable comb is easy to use and I don't have to dig through the drawer in the bathroom to find a snap-on #3 comb I like to use and therefore always lose. The vacuum feature is nice and makes cleaning up small jobs easier, especially since I don't have to sweep hair off a wet sink afterwards. Cleaning is straightforward as all the pieces come apart and go back together pretty easily. The turbo feature is also helpful. My beard is very coarse, and tends to jam up most trimmers. This one gets hung up sometimes, but if I go slowly and don't try to cut too much at once, it works fine.
One note: The hair "reservoir" under the vacuum fills up quickly, so it's better to use this more often on smaller jobs than waiting to do a bigger trim.
