I use a Philips series, I forget the exact one however it has multiple levels to adjust the head to built into the handle.

Been using them for years and they've never done me wrong. They charge quite well, and my current one maintains enough charge for a month or so of trimming. They're very easy to clean, don't cost an arm and a leg, and on top of this the trim is consistent every time even after a year of ownership.
