I ordered two of these 3D-backs for my Juwel Aquarium. Optics is nothing premium and the price anyway but the jewel priced were not the cheapest. The crop is a disaster. With the utility knife it is by no means. The surface shatters and crumbles partially from. Is it possible to bring very difficult to measure. State after 3Monaten: - Plates are bent (no idea but not enough so as to bend whether by hiztze although 24 degrees is a plate!) - The cleaning of algae infestation is impossible - The jewel original silicone is unusable and peels off - Plates are lighter so that when the silicone stops to keep as Diving literally out of the water the. - All kinds of residues, dirt and snails crawl behind the walls where you can of course not putyen because it is glued
CONCLUSION: very high price for such a product. NOT BUY recommendation !!!! Waste of money !!! Go back to adhesive film on the rear wall.
