Very disappointed 83

I cut my hair for years now, a number of mowers have passed in my hands. This time, I was expecting a quality product saw the glowing reviews, unfortunately I soon realized that this mower does not satisfy me. I used to cut my hair short on the sides, I have thick hair and the cut was very tedious, forced to move several times to get a perfect mowing, small hair behind the ears are hard to cut and there is no way to make a gradient behind the neck, finishes are not ideal. I find that power is limited on battery (I had yet to charge max), I had to reconnect the cord to finish. The mower is delivered without cover,
