They are OK and do the job, they are actually quiet!

I cut my husbands hair every now and again, I used these to do it yesterday and they are actually quite good. He has a Philips as his usual clippers, they are great, these are good too obviously no as great as the Philips but they do a good job that is more than satisfactory, he doesn't have 'hair' and shaves his head to the smallest grade. I can comfortably send these with him when he's away working knowing that if he looses them it's not a big deal. They are indeed quiet, I was surprised. I wouldn't say they would wake me if he was using them while I was sleeping, he could use them in the en suit and I wouldn't stir (sometimes he leaves in the middle of the night hence the necessary hair cuts unexpectedly )
I am going to recommend these as a spare set for anyone looking for a clipper that they can reply on whilst away from their humble abode. Good value for money and a great gift too for any students leaving home.
