Review title is Great hair cutter, easy to use. [SEP] My wife is a professional hair stylist. She cuts my hair every 2-3 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 40 minutes of time per charge.<br /><br />The 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 6 or 7 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 1/16 of a inch up to about 3/4 inch, and the long variable one goes up from there.<br /><br />Having the variable length guards is great as it reduces the number of guards you need and allows you to change lengths on the fly.<br /><br />Using the shears without the guard is also good for trimming to the skinline, edging and shaping.<br /><br />The only complaint my wife had is that she wishes it were a little more powerful on battery, but wasn't 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 like.<br /><br />Overall a great shear for home hair cutting.
