The battery is long lasting and the charger works well. The variety of settings isnot always necessary, but gives a good selection in relation to the area being treated. Seems to be helping me deal with some real knee pain that has come from arthritis and other problems.
The Light Therapy Torch is used by our family for injuries and lingering aches and pains. It is easy to use and we feel the difference after following the recommended use. Great product.
I have just purchased this and have been using for 1 week now. I love it so far, feels good and my husband says his knew that I have been treating is better as well!
