Summary: First off let me say that the screwdriver that comes with it probably doesn't work. You need a #5 torx. Other than that this kit was very easy to install and was of good quality. I was surprised to find out that the lense covers are nearly ¼" thick.
Summary: This is a good product to get when your GoPro needs a new lens. I had been coping with a scatched lens for about a mounth and I counldn't stan the blur any longer! It was easy to replace the old lens as all the equipment was in the package.
Summary: The lens is good quality. I did find the screw driver pretty useless as the handle twists as you try to undo the screws, binned the screw driver and used one with a good handle. Seals are 100% waterproof, test it out by going Kitesurfing in Gale force winds and 8 ft waves, no leaks.
