I seen the coupon for these a while back and have used many hair clippers as and I do have facial hair and I like to keep it nice a trimmed and these have got to be the quietest yet. I think this is because the metal and there is some sort of tuff plastic, so this stops the vibrations. The cable to use wall power and then 2 baterries if you go on a camping trip which i love to do and this is perfect. It could do with having a blade 1 and 2 but the adjustable blade give you the amount of length you probally need.
Overall the trimmers are really good quality and easy to use they adjust with a twist of the neck just below the cutting blades and if you are using them for hair or beard these are going to do fine. I would sugewst purchasing blade oil to keep the blades nice and smooth and they should last for ages. I dont know how long the batteries will last but they have lasted a couple of facial shaves, so Im thinking they will last as long as I need.
Like I say overall excellent clipper, trimmers what ever you call them and these are well worth the money and are as good of the other expensive models, thats upto now. Great : )
