Review (4/5): Works perfect for me, but not perfect for everyone.
I love shaving in the shower. This shaver works great for that purpose. I don't use the propriety Nivea shaving moisturizer; I just use a small dollop of Nivea's regular shaving gel ($3 for a large canister available anywhere) and that works fine. It is a little slower than my old Norelco Advantage in that it requires several passes over an area to get a nice shave. The flexible head design is amazing; it can really get that stubborn neck hair that my old shaver used to miss. The open design makes it not that great for dry shaving as the hair gets everywhere, but I use it 98% of the time in the shower that that is not a big issue for me.
The reason for 4 stars instead of 5 is due to it's charging mechanism. Charging the shaver in 4 hours sounds like a good idea, but the manual strictly admonishes against overcharging. Hence, it is actually a bit of a pain. If I bought the low-end shaver that charges in 8 hours, I'd charge it in the morning and it would be ready when I get home from work. If I bought the high-end shaver that charges in 2 hours, I can plug it in whenever I feel like and unplug it 2 hours later. A 4 hour charging time requires a larger block of time for me to have to remember to charge the thing. Why couldn't Norelco make a charger that automatically shuts off or goes to trickle charge when the battery is full? Also, why the need for a base? It takes up counter space in my bathroom and is bulky for traveling. My old shaver did not have a base and was great for travel as the AC adapter plugged directly into the razor.
If I had to do it all over again, I'd probably buy the 8020x and save myself $25.
