Quick and Easy
I was skeptical using this at first, but wanted a way to quickly shave my head.  Ordered this from Amazon and just used it.  It worked extremely well.  Took me about 10 minutes to shave my entire head.  With the pro version, you can quickly just wash the heads by putting them in the sink.  I am extremely happy with this purchase and would recommend to anyone who wants a fast / thorough shave.
