Good product. Bad packaging. Mine came and was sealed with electrical tape. By the time I got it off it pulled the cap off with it and I lost about half the product. Oh well, it's inexpensive enough and I will be more careful next time. Otherwise, the product is as described and as long as you use it correctly you will get the same or better results from products that cost ten times as much!
