I have three enclosures that require heat mats. In the last couple of months I've had to replace all three of them. One was an Exo-terra brand, one was an expensive Zoo Med brand, and one was a generic no-name brand. I'm wondering if this is typical for them to only last a 1- 1.5 years? I also wonder if they are breaking because we have them attached to temperature regulators, so maybe they turn on and off frequently, and this causes them to burn out faster?
Any thoughts or suggestions for replacement products, or how to keep them lasting longer?
