“The product is good, but the creators should have thought more about the condensing water, that is always trapped inside, since it is always in the air (if you don't want to find yourself tinkering that stuff together in a cold room).
I had to put a defundable ring filled with silicate dessicant inside the camera half sphere, so it would not collect dew drops in the morning on outdoor usage. The rubber slit has to be sealed with silicone too. Big downside is the image sharpness, that the dome produces. For underwater footage maybe good, but haven't tried it for now. Considering the price and the delivery costs of all together almost 60€, I would rather 3d print something similar myself.”
