This is one of those occasions where I am astonished that anyone could give this product a positive review - let alone multiple five-star reviews!
It doesn't cut hair. The main problem is the adjustable, pivoting comb - a good idea in theory, but a complete disaster in practice. It jams up with hair after every cutting stroke, blocking the blades. I have moderately thick European hair - nothing unusual - and even with a clean comb, the blades can't get through denser areas of hair cleanly without grabbing.
First attempt at a cut left me looking like a member of the 80's band "A Flock Of Seagulls", the clippers couldn't deal with the crown of my head at all. Fortunately I hadn't thrown away my old Remington clippers, which despite a knackered battery were still able to finish off the cut. Those clippers have a traditional set of combs and a much heavier duty cutting blade - the Philips' blade is in a plastic housing.
Avoid, avoid, avoid. There is no doubt a reason why barbers use the traditional style of clipper. I'm astonished Philips let this piece of junk get beyond the product testing stage - or perhaps they don't bother with that any more as they try to cut costs?
