Brilliant to use, but not perfect...
I have used this model of Phillips clipper now for the last ten years - brilliant design, with the rotating head. There are, however, two manufacturing issues which Philips have known about for years & do not seem to have made an effort to fix (big companies, eh?): 1) The battery lasts between two and three years, with an average use of once every 10 days; then it just gives up and refuses to take a charge. The battery cannot be replaced, so the whole unit needs to be junked. 2) The Precision Comb attachment is fragile (I have short hair and have never used the Big Comb). I broke two of them before I realised that you need to reset the length to shortest before removing the comb. But Philips do supply spares.
If you accept that you may need to buy a whole new clipper every two or three years, it's well worthwhile. List price now (Nov 2020) is around £70, but I have always managed to pick one up for around half price, and you can build up a supply of spare attachments (including the rotating head & blades, which are removable) by cannibalising the old ones. Last piece of advice - after 18 months, start looking to buy a new one going cheap, BEFORE your current unit packs up in the middle of a trim, with no back-up to finish the job.
