I recently bought it, I have shaved my head 3 times and my neck 2, I have to say that I was very afraid to buy it in case it didn't turn out good and I researched a lot, but since I saw that there are also spare parts available, I decided to buy it. So, for shaving my head, it works very well. I had hair and I had taken it down with another machine before, it was just barely left. When I bought the BaByliss, it needed quite a few passes and slowly I learned how to use it, but I get it done very comfortably. Just if you have hair, it requires patience and a little cleaning in between, which is nothing, as well as for the neck. It will make your life easier if you do the first and second passes with the direction of the hair and from the third pass against the grain with a gentle pressure of the machine, the result will be baby smooth, guys! It should be noted that I have a mole and a pimple at the back of my head, but with caution, there is no issue of cutting yourself. I believe that you get what you pay for, and this device is worth its money, especially when you know that there are spare parts and it will last you for years. Although it is square, it is very convenient to hold, and its construction is sturdy and of high quality. Now, I don't know if the UV light does anything, but it has a little flair and you look a bit cool if you're a gadget lover... I hope I helped, guys, and I'm not getting paid for this long review, but since I also took my time to decide what to buy, I thought I might help someone with my comments to reach a conclusion..
