I've had two of these screen protectors, the first one saved my watch screen from being shattered. I found flolab through a review on youtube, and I will continue to shop with them. When my first screen protector broke, I sent them a picture and they sent me a second one for free (except shipping). Totally worth it. It is very easy to put on the watch, although removing bubbles is a bit of a pain. There are some good videos on youtube to help with this problem, but I do currently have a very small bubble under my screen that I can't get rid of. It's almost undetectable, so I don't really mind. My favorite thing about this screen protector is how when it is on my watch, I can barely see it. I wanted a screen protector that would do it's job, but not be a bulky addition to my watch. I love this one, and would definitely recommend it.
