Review on AquaIllumination Prime Tank Mount: Enhancing Your Aquarium Lighting Experience by Kathy Bishop

The key to this product is NOT to over-tighten the screws on the ball joint. I tightened just enough to hold the light in place. I don't experience any sagging or anything like that with the light. I love the modern, sleek look it gives my tank. And it seems that the lantern is built into the tank itself. I have not noticed any disadvantages in this mount for the tank. It's definitely worth the money. If you have an AI Prime LED I would recommend it instead of the flexible arm. Especially if you want your aquarium to look stylish and modern.
