There are several things we use for keeping reptiles that weren't designed for it. For example, Rubbermaid and Sterilite tubs, the Ranco and Johnson thermostats were designed for commercial heating and refridgeration units, the Acu-Rite thermometer that alot of us love, is a indoor/outdoor thermometer for a house, but hey, if it helps keep my husbandry where it needs to be, then I'm good with it...
