I was hoping it would last longer...
At first I was super happy with this purchase. My glasses were constantly slipping to the point where I was ready to toss them.  And these definitely do what they promise - I hardly had any slippage once they were on. However, I was hoping they would last more than two weeks. I was disappointed when the actual silicone detached from the adhesive. So in no part did I do something wrong with application (they won’t stick as well if your glasses are dirty or oily). Nope, the actual product fell apart. The adhesive was still stuck to my glasses and took some elbow grease to get off.  I didn’t expect them to last forever but I was hoping for a bit longer than two weeks.
