So , I just finished building an addition on my snake building that will be utilized as a quarantine room . So I found myself needing a thermostat to control my heating devices . I gave Rich Goldzung a call over at Reptile Basics and talked about the Vivarium Electronics 300x2 dual zone temp controller . I've ordered a lot of things from Reptile Basics over the last couple of years and they always meet or exceed my expectations . I'm not sure how they ship so fast but my package always arrives sooner than expected . If your not doing business with Reptile Basics you should !
