Product was labeled for sale only in (some non-US country, don't recall where now) and wouldn't install, so was essentially worthless. Neither Amazon nor the seller tech_direct would do anything about it. Won't buy software from either again.

This product is great for hair growth, but it causes acne. If you're one of the unlucky humans who have to deal with acne, I recommend taking this in increments. I would take it for a week then wait a week then take it again and so on. Even on medica websites, biotin is listed to cause acne in some. My hair grew about an inch for the while I took it but I didn't finish the bottle yet due to it making my acne worse and cause breakouts where I normally wouldn't have them.

Decent quality. I installed it on a 2016 Explorer. The directions don't exactly match up to the 2016 model, but I was able to make a solid install nonetheless.

I find Neutrogena to be a dependable brand, but if it really did get rid of deep wrinkles one could not afford to buy it, because it would be magic!. I will just be happy softening the fine wrinkles (don't know what I would look like if I didn't use it).
