"This is a good product; I use it for my ball python, Stewie. Plugged into a rheostat [good, cheaper alternative for a thermostat] it doesn't get too hot and I can easily adjust the amount of heat I want it to put out. Just be sure to keep in mind that when using plastic tubs to house your reptiles, it won't melt, but it can be warped; warping is bending.
Also, remember you don't have to use the adhesive on the pad to use it. I just used tape and attatched it to my python's tub. That way, it can be easily removed when I need to wash the tub. It doesn't put out much heat so keep in mind that, depending on your reptile, some kind of overhead heat may need to be provided. With a rheo/thermostat and a good digital thermometer, you can be sure that the heating pad will work great."
