Review on Zilla Fresh Air Terrarium Metal Screen Cover with Hinges (30 X 12 Inches): Superior Ventilation for a Happy Habitat by Jared Winebrenner

Overall I like it. However, for a length of 20g, this is not a comfortable fit. I bought braces and used them; However, there were gaps in each corner and protrusions around the perimeter. I was unaware of all this when I bought and received my first pink boa (1 month old). She ended up running away and we never found her. Using tape around the perimeter of the tank and air duct to route the wires (thermometer and thermostat) and 10 clips to hold the lid in place, I made it secure. The metal is also not as strong as we would like, with DHP it will warp a bit. If you make provisions for very small reptiles and really watch the fit, noticing gaps and overhangs, it will work; The hinges are great as I don't have to move the DHP or light from the back of the tank to gain access.
