15 years of use

After 15 years of use, I finally have to look for a new battery for my GMT 180. It's worked like a champ for all that time. It handles my very tough beard really well, and never runs out of power for the 15+ minutes I take to cut/trim my beard. Maybe it's not as powerful as a corded clipper and thus might take a little longer to do the job, but I think that's a plus - a slip of the hand doesn't gouge out a huge section of beard.
