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 bladeson 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 onethe 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 years old figured the battery did not have much life in it
