It's starting to work after 30 days, this stuff works and I take a few medications. I was on expecting it to work and instead wait until I notice any improvement and -- TADA! I can see better. Thanks Amazon !

I was extremely pleased with this product for the 2 months that I got to use it. It has since broken and I am not sure why, it just sits on my nightstand and suddenly it stopped working. I tried changing the battery but that also didn't work. I guess if you only need it for a short period of time this would be great, or maybe the one that I had was just defective, I am not sure, but I am not pleased with it.
