Review (3/5): How do you know if its on?
The product works well, however the application is questionable. I spent 10 minutes each night trying to apply the product on a few spots and I never knew if it was on or not or how much was applied. The roller ball needs to be improved on the same level as the yes to tomatoes spot treatment. If you need a cheap, well working spot treatment, I would recommend this. If you don't want to deal with the hassle or question the application, then I would look elsewhere. Needless to say, I am not buying this product again.
