I was really at odds here with this item. On the one hand, I really like that it gives me a unique perspective on the video I can record with my gopro. On the other hand, if it wasn't for my burgeoning hobby of vlogging and amateur video I would have probably passed. That, and living in a place that is too cold to visit lakes and oceans also puts a damper on it.That being said, I really like this device/waterproof mount. The gopro is already waterproof ( hero 5) but what this does is allow for a very unique look under water, while maintaining above water view. you pretty much get the best of both worlds. I didn't get to try this in the ocean, however my relatives swimming pool worked just as well. The lanyard made me feel comfortable that I would not lose it, and the handle is large enough to get a great grip, without it being too large. The front cover is outstandingly clear, however I feel like through normal wear and tear it will eventually get scratched, buffed, or hazed in a way that may degrade the quality of footage you record. I would recommend cleaning after use with a microfiber and a safe cleanser of some sort, either just soap and water or a vinegar based mixture. Avoid the abrasives if you can.I will keep this in or near my travel bag in the event my travels take me somewhere where I can use it. It offers a fun different style of view that canhave a very beautiful outcome.
