read all instructions and this product will work if it does not burn your skin. However try it on a small area of skin before using this in a large area to see if you have a bad reaction to this product.

Like other reviews, the instructions provided with this product are minimal at best - but this is a very good product and a very good value given the price. I was prepared to spend more - but now seeing the product and comparing it to others there is no need to do so. I am very mechanically inclined but even if I wasn't the installation should take no more than 30mins. My suggestions to make your install correct and easy:

The first one I bought stopped heating after a short use. The company was gracious enough to replace it-only after I jumped through the hoop of submitting photos of the broken unit with the power cord cut per their request.
