I absolutly love this little thing. The emjoi really works. It is definately worth the money. The Emjoi pulls hair out from the root. It really leaves your skin smooth and the results last a long time. It is great for touching up sections of you legs, underarms, and bikini line. This emjoi is great because it not only works great but also is very tiny so you take it with you when you travel. You can even keep it in your purse because it is so small. Don't let the size fool you. Even though it's small it is very efficient. The price is great too. It is only about $20.00. It is very hard to find in stores though. I found mine online. The only draw back to that is that you have pay for shipping and handling which cost me 6 or 7 dollars. It takes two AA batteries which will last a while. However when the batteries start to get low you will notice a difference in the perfomance. You may be a little scared by the noise this little thing makes, but don't be scared of it. It does hurt a little but no more than tweezing or waxing does. The more you use it the less it hurts each time. The hair also grows in finer after long term use. Although after using it you will want to exfoliate to avoid ingrown hairs. This work just wonderfully. I don't know how I got along with out this thing before. Definatly give this thing a try!
