I got this as a gift and it served it me well for approximately 2 years before everything started dying.
First, the shaver wouldn't hold a charge for long (maybe ten minutes at max). This wasn't such a big deal since I require less than a few minutes to shave so each day it just goes back to its cradle right after.
The second thing was that every few weeks, the cradle would not hold the shaver, as in every time I press down on the blue button handle thing on top, it just pops off. This would go on for two to three days and then all of a sudden, things go back to normal. Again, irritating but I could live with it. After all, the thing (luckily, gift) cost over $200 new so I tried my best to live with it.
The last issue that eventually led me to replacing this guy was the electric motor itself, it just got slower and slower until every now and then I would get a hair pulled out of my face.
With that said, during the first 2 years I've owned the shaver it performed well, the cleaning system is nice too.
Honestly, I could not get used to the tri-circular blades. It just doesn't mold to my face and I end up using just one of those circles most of the time.
