I bought these about 6 months ago and they worked great until I took these 'waterproof' goggles to the pool for the first time last week. They honked long just after the pool and have been dead ever since. I also couldn't recover any of the videos I took with glasses on vacation. It's almost impossible to find contact or warranty information from this company - looks like they don't even have a website. Be careful with the waterproof claim. I'm only giving these two stars because they were great when they worked, but it's too expensive an item to die in 6 months (and take all your videos with you).
