Buy this, it works!
First of all, very fast shipping. Now to the product, yes it did help immensely with removing most of the odor. There is still a slight smell left, but I can now drive my truck. I think I'll do it once more and for longer, (did 10 hrs). I would highly recommend this product because it worked. I do think written instructions should be included, not everyone wants to waste time with having to go online.
