Review on Protection Anti Splash Accessories，Reusable Accessories，Suitable Occasions by Matt Watkins

This works well to keep my glasses from fogging up as long as they stay in place. It moves when I speak, yawn, sneeze and sometimes when I close my glasses. Sometimes it shows up and I have to take my mask off to fix it. Thankfully, I don't find it too difficult to take the mask off (I don't have to tie mine). Attaching this clip isn't the easiest thing so it's a little fiddly to fix, but I'm glad I have anti-fog goggles so I can fix it from time to time now! Also, it's soft silicone (in the picture it looked like hard plastic to me) so very comfortable!
