Perfect fit, looks perfect, doesn’t feel cheap, is perfect quality, literally everything that can be good about it is and I love it. I’m trying to set up a crested gecko enclosure and I’ll be getting a baby so I’m setting up a 10g and this was perfect. The tank in the pictures is not set up yet I’m working on a concept of what the actual enclosure and the moss will just separate the drainage layer and substrate more than the actual divider does. Also I taped it because I don’t have silicone yet and the light will be changed to a uvb. This is really secure and i definitely will be using it again if I need to.
