This is a very unique trimmer and I really like how well it works. It has a sleek and modern design and is a sturdy little device that is very effective at removing unwanted hairs. It is well made, quiet and easy to use and clean. This trimmer fits nicely in your hand and has a good, sturdy feel to it. It uses USB charing and has plenty of power to cut quickly and cleanly. I like that I don't have to keep buying batteries and it charges quickly when I need it. The power button is unique and you just lightly push the buttom on the base to turn on the power, the LED display will light up the "NOOA" logo. Then you press the sensing area ( white line on the front of the unit ) for 2 seconds when you are ready to start trimming. It takes a time or two to get used to starting it but I like how unique and different this trimmer is and it works like it should.
