It's okay
You have to realize this is essentially a glue stick. I got this and quickly realized this wasn't for me. The adhesion was okay. I thought it was going to be stronger or something. I'll admit I didn't know what I was hoping for when I got this. I won't say this product is bad. It just so happen that I got LASIK so I didn't need my glasses anymore or the product. I wish I had this years or months before I bought this to really try it. I would say the thing to think about when using this though is that it has to stick to itself. Meaning a layer on your glasses and the bridge of your nose. In that regard it works fine. If you don't wipe your nose and only apply on your glasses it could slip a little, but works best when you have enough of a layer on both.
