Review (3/5): Almost but not quite
I bought the 9170XLCC and I found that the shave was very superior to my old Norelco from 5 years ago.
However the cleaning system seems to be buggy. I had to return the first one I got because after 2 minutes it would just blink forever.
I just got my replacement and while the shaver is still great, I am having the same problem. This time I let the lights blink and eventually after about 45 minutes it said it was done. This is far more than 2 minutes.
