I was surprised when receiving that it had 4 large suction cups to attach to the tank wall. It seems so much more sturdy then I was expecting. Very happy with my purchase!
This is a great buy, I’ve compared pricing online and this is a great deal. Thick plastic, great quality. I would have given 5 stars but the suction cups kept falling off and wouldn’t stay. It was frustrating but not the end of the world. I would buy another one.
