Review title is JUNK [SEP] I knew I was in trouble when I opened up the box and there was an empty compartment.  I have no idea what was supposed to be in it.  I then saw that the on/off switch was crooked.  Not a good sign.  I put fresh batteries in the shaver and turned it on.  Nothing.  Completely dead.  Tried again and again and eventually it started up, but was very weak.  Tried again and it worked, a little stronger this time.  Started using it, and it died.  So, in a nutshell, sometimes it works, and sometimes it doesn't, and when it works, it's so weak that it pulls hairs, instead of trimming them.  I wish I could give this piece of JUNK zero stars.  I honestly don't understand the great reviews.  It was a total waste of money for me, and I wish I could get a refund.  I'm now stuck with a useless piece of garbage.  This manufacturer should be ashamed of selling such a horribly cheap item.
