It's been a full week since I received my Sonic Groomer, and I have been using it a lot. It has two full recharges (comes with rechargeable Lithium Batteries). Each charge lasts 45-60 minutes. Initial charge takes two and a half hours.
If you can see it, you can remove it easily and pain free. If you can't see, but it's within reach, you can remove it, but might knick yourself, although it's not too painful. I have removed hair from my knuckles, toes, above my feet and on top of my hands. I also used it on my groin area (including sensitive areas), my lower backside, the back of my neck, and my entire chest. This trimmer has also become my everyday electric shaver, it's as good as any electric shaver on the market. I trimmed my mustache with it, and the end result was the best trim I have ever had. It took about two minutes.
I was more than willing to try this product and return it if I was not satisfied. Personally, I'm thinking about buying a second one because I don't want to ever be without it. Just so you know, some of the websites that review this product do not show the positive reviews, because they obviously want people to think that this is not a good product. But that is far from the truth.
Bottom Line: Yes, I would recommend this to a friend
