I bought this product today and used it right when I got home for my legs and arms. It is true that the product does burn....a little. But after about 30 seconds it dies down and you can't feel it anymore. Unlike the reviewer above I have thinner leg hair so it might have something to do with the thickness of body hair. Depending on where you use it. Same applies to the irritation. It didn't irritate my skin but it might depending on the person who uses it.
