Wizzit doesn't have a luxurious feel, which is why I've given it four stars instead of five, but it is so cheap that it wouldn't be fair to complain about the fact that it's a bit plasticky. [Mine was £10.99, by the way.]
Provided that you hold it as recommended - at ninety degrees to the skin, with the logo facing away from you - Wizzit works efficiently, and finds hairs where you didn't know you had them. Unlike tweezers, it is most effective on very short hairs, which are pulled out with a prickling sensation. Longer hairs are a little more painful (same as with ordinary tweezers), so you might suffer a bit the first time you use Wizzit. After that, using it "little and often" removes hairs almost before you know they're there.
PS. 13 April 2011: It is now over a year since I bought my Wizzit. It's still working perfectly and I wouldn't be without it - in fact, I've just bought another. However, I've noticed that on the outside of my new pack the Wizzit is advertised as "perfect for both men and women", while the instruction sheet inside states that it is "NOT intended to remove men's facial hair". I don't expect that many men will think of Wizzit as a replacement for shaving, but I still think that the packaging blurb is seriously misleading.
