Review (3/5): After less than 2 years, it will not turn off.
I would rate it at 5 starts except that the power switch is no longer working. I expect a razor to be trouble free for 4-6 years.
Could it be related to the water cleaning? If I was careless it would have shown up in the first few days or weeks. It seems to me that a minute amount of moisture can seep down the back--into the trimmer area and then what may happen over time?? Or did the switch go bad? Or did some water get into the switch? How water proof is it over the long term?
