The build quality of this product is very high and it seems to be a very solid product for its price range. I think this is a must have accessory for the GoPro Hero 5 Black as not only is it good for underwater photography but it also comes with a waterproof case (not that the Hero 5 needs one as it comes with a waterproof rating of up to 33 feet). but it's just an extra precaution in case of deep diving over 33ft gopro! Although I checked the included handle to see if it was a floating handle, I don't think it would be enough to pull the weight of the dome to the surface if dropped. In my opinion I would take at least 1 or 2 gopro floats and tape/tape them to the back of the canopy to make sure it doesn't get lost underwater when dropped! Great product, I recommend it to everyone!
