Query: Shaves Great, Breaks Often

When I first tried the shaver I was beyond pleased. What a great shave! It was very quiet. After a month the motor started bogging down. Even with ongoing careful cleaning and proper charging of the batteries, the shaver eventually refused to run. Customer service was obsessed with charging. Did you charge it for more than four hours? Then plug it in again and charge it for only four hours. That made sense to them. I sent it back and Norelco sent me a new one. The new one lasted as long. It is now beginning to slow and bog down. I just ordered a Panasonic. I cannot get up one morning to find this shaver refusing to shave. I should not have to have a spare to fill in between service calls.
