3D Background For Tank

I was wondering if anyone has had any experience with products like this?

I was considering it for my axolotl tanks, but might also put it in my 125L tropical tank so I can attach some plants at the top to keep the silver hatchet fish happy.
Any comments or advice would be very welcome.
Thanks.

Thanks Sue.
It was primarily for the axolotl tanks, and they are quite big fellas. Mine also seem to have a habit of "swimming" with their legs, and by holding on to stuff, rather than using their tails (not the brightest animals), so I thought a textured background might be helpful.
With the 125L tank, it is currently quite understocked, but I'd hate to lose too much space, so I think I'll give the 3D background a miss here, and just stick with the floating plants for the hatchet fish. They seem ok with them, so I think just more of the same (fish & plants) will be the way forward.
 

I eventually went for this one because it wasn't as deep, so would take up quite so much space in th tank.

I'm in the process of fixing it to the new axolotl tank. I attached it yesterday, and when inspecting it today I've decided I need some sealant around the edges, especially at the top, because the axolotls have very delicate skin and I don't want any rough edges.
In general I'm quite pleased with the way it looks in the tank, and look forward to planting the tank and transferring the mature axolotls. Then I can empty that tank and attach the other 3D background, plant, and transfer the juveniles.
