Theyre okay. I bought thrse because the X4 came with standard lense guards and i was getting a glare. Im still getting a glare with these although its not as strong. Tbh I dont feel like these are a necessity and theyre the same as the standards which you get for free.

These lens guards have stayed put through lots of snowboarding. Great upgrade over the originals that fell off on the first day.

These are pure garbage. I took one off because yhese done seal at all causing lots of pollen and trash to get between the lenses. When i took it off it fell i put my foot out which it hit first. Then it struck the ground and cracked straight down the middle. They lasted one use and not one attempt at cleaning. What a joke. These will not protect your camera at all. And likely to cause issues with the amount of trash that can get between your lenses. I highly recommend spending the money on something different.

Work well with product and fit like a charm good value

strong enough but there is a glare sometimes. get this if you prefer security more than the clarity
