Purchased this to go in a vivarium with a Chinese water dragon. It's easy to bend into a shape but be warned that too much bending will cause it to split and expose the metal inside and of course once it is exposed it could potentially be a hazard to your lizard.
It is also much shorter than it appears, I never pay attention to measurements which is entirely my fault but I bought it in store and it looked longer than it is!
It looks relatively natural if your environment is more jungle themed. I probably wouldn't put it in with my bearded dragon for example. I would suggest creating an area with a few of these twisting around, I think that would look attractive. As well as looking pretty good they are, of course, quite fun for your lizard. Having a Chinese water dragon I knew she would love to climb so used this to wrap around a much less grippy branch and it soon became her favourite climbing branch!
Overall I think if you are willing to purchase a few of these and get creative with shaping them they would be a great addition to your vivarium.
Exoterra is a very popular brand when it comes to reptiles but I do think they charge a little too much for the privilege. It's not the cheapest thing but as I said before, put a little effort into your decorating and there is definitely a place for these vines.
