Review (4/5): quiet and convenient
This razor is my second norelco rotary, my first is a 5100 series about 20 years old. Compared to that, this razor is much cleaner, quieter, and more comfortable. The new razor doesn't *sound* like it turns the blades as fast or as powerfully as my corded dinosaur, but it seems to me that it cuts more effectively, which is what I hoped for.
Cleaning this new razor is a breeze - just a quick rinse under hot tap water and I'm done. Having cleaned it this way, I can't imagine paying for the extra cleaning station and chemicals - I note with some interest that the printed user instructions and website FAQ also recommend the hot tap water cleaning method...
Comparing my shave to a triple-blade disposable system I use, the electric doesn't cut quite as close - I can't tell immediately after shaving (my face feels smoothly shaved in either case), but I notice stubble somewhat earlier with the electric razor.
I shave about once a day - maybe 5-10 minutes or so. So far, the battery life is about a month as advertised. Very convenient indeed.
