I have owned a Finishing Touch Personal Hair Remover for a few years now, and I really like this little gadget. It is a very compact little razor which removes hair painlessly.
I have used it on my chin and upper lip the most, as these are places which are very sensitive for me (I have rosacea) and I absolutely cannot use wax. It is also very effective on the bikini area, feet, ankles and other areas which are hard to manage with a larger, more cumbersome razor. My Finishing Touch also came with an attachment which allows you to groom your eyebrows, but I haven't actually used the attachment. When it comes to my eyebrows, I still use the good ole tweezers.
This small razor is very easy to use, and its compact size makes it easy to hold. I find that hair will grow back in about the same amount of time as with a regular razor, but since this gadget is so easy to use, that doesn't bother me. It can even be slipped into a purse or pocket, so that if you want to carry it with you somewhere, it is not a problem.
I definitely like my Finishing Touch Personal Hair Remover. I use it quite often, and the one AAA battery that powers it lasts quite some time. Definitely a winner.
Update On Apr 03, 2009: I just wanted to clarify that this isn't actually a razor, even though I referred to it as one. It has a small blade with teeth that moves by battery power and removes the hair painlessly. I also experience absolutely no irritation with this great little gadget.
