great hair cutter easy to use [SEP] my wife is a professional hair stylist she cuts my hair every weeks and relies heavily on using electric shears to do so this unit works very well it can work plugged in or with battery which should give you about minutes of time per chargethe shears are sharp and do a great job of cutting through my thick hair the attachments are also very nice unlike other units that have or different guards depending on what you want to do it has a fixed length one a short variable one and a long variable one for my hair she used the short variable one the settings go from of a inch up to about inch and the long variable one goes up from therehaving the variable length guards is great as it reduces the number of guards you need and allows you to change lengths on the flyusing the shears without the guard is also good for trimming to the skinline edging and shapingthe only complaint my wife had is that she wishes it were a little more powerful on battery but was not really lacking in power it is just that she usually uses professional shears this unit is actually as powerful or more powerful than most shears you buy at walmart or the likeoverall a great shear for home hair cutting
