Design problems but a good product [SEP] I own an earlier model of this trimmer and over all am happy with it. The only issue I had with my old one and this model which I just purchased is the "door" in the front just under the cutting blades.<br />On my first one, the spring hold the door up broke allowing it to drop and lose much of the vacuum.  I was not really excited about purchasing another model with this same design but because the overall trimmer function has worked well for over four years decided to purchase a new one.<br />The only reason I purchased a new one is the charger broke and I had no way to recharge the battery and because it was over 4 years old figured the battery did not have much life in it.
