Non-Stick Premium Heat Mat
Fluker's Non-Stick Heat Mat is a great alternative to the Zoo-Med ReptiTherm. It works well for enclosures that are moved on a regular bsis, such as Dubia Roach bins, Cricket enclosures, Isopod Cultures etc. This comes in multiple sizes, and we stock two of them all the time, the Mini (4x5), and the Small (6x11).
We recommend always using a thermostat with your heat mats, in case anything ever happens, the thermostat will protect you from potential fires, or burning your reptile.
