Review (2/5): excellent, shaving but there's a reason it's cheap
I had another Norelco shaver for the last 5 (or more) years. The difference in the shaves is striking. Both less pain when my stubble is a little long and closer.
However, the reason this shaver is cheaper is that there is 1 battery inside it instead of 2. I know this because I took it in to be "repaired" because I only got 8 shaves to a charge. I talked (online) with Norelco and they said my shaver was broken. So, I looked up on the Norelco site a local authorized repair shop. I took it in and the guy opened it up. He said it was one of the "cheap" versions that has 1 instead of 2 batteries.
My old shaver, over most of its life, gave me 25 or so shaves before needing to be recharged. That's quite a difference.
