With only a couple of swims under my belt, there is a marked improvement in leakage and fogging. Comfortable on my eye socket/face and the goggles come with additional nose pieces. Product is 'hair friendly' and attractive. It took me a while to figure out the straps, but I 'get it now' and like them.

Ex Output:
positive

This is our second Netvue camera, first was a indoor one, the picture quality and voice are perfect. It's super easy to install and customer service is great if you have any question on the product. Love it so much getting 3 more as Christmas gifts.

Works great for hanging my concert ukulele. Easy to install. Stays well in drywall. Neck sits perfectly in the grippers, which are padded with the coating.
