I had bought a Philips S5420/06 to shave my head but it didn't work for me at all. So, a friend of mine who had the Andis tells me that it's amazing and shaves like a razor. At first, I didn't really believe him but I thought let me buy it and see if I can avoid the razor, the foams, and all that shaving ceremony that resembled a summoning of spirits. What I have to say is that if you buy it, you will be completely satisfied, it provides a very close shave almost like a razor and it doesn't pull anywhere. It also works with its power supply, while the Philips S5420/06 couldn't be used while plugged in. The downside is that it only has this head and it doesn't have any attachment that you can attach on top to do precision work, for example, for sideburns, but that's a minor downside compared to the result it offers you.
