Yoss - yes it's evolve and I got it at Walmart it was a dollar and some change. Glad to know it works decently and for the price can't ask for a lot lol.
Skorpio - just like yoss said I got this one at Walmart but I have seen heat wraps at Sally's. I figured I would give it a try since it's really cheap.
This is what it looks like
Here is the link to the one on Sally's. They sell the evolve too but it's more than Walmart. I think they have it at 3-4 dollars.
