works okay
I have tried other silicone stick-on nose pads and have written reviews for them.  I felt these were better than the other two that I tried because it was thinner and didn't look that thick when on my glasses (although silicone, you can still see I have nose pads on my glasses since my frames are black).  In addition, these didn't leave a sticky goo when they were about to fall off.  As for duration, it lasts about the same amount of time as any of the other stick-ons (~2 weeks).
