I've seen both being used, although most reviews I've read have said that the ExoTerra under tank heaters (rainforest especially, desert ones arent as bad) do not get hot enough. Im currently using the Zoo Med Reptitherm, and its working really well; HOWEVER, they dont sell them anywhere in Toronto and I had to get it shipped from the states.

SO, I wanted to see if anyone uses the Exo Terra Desert model and do you have any problems getting it up to 90-95 F ? These are a much cheaper option for me and very easy to obtain since they sell them at every single Petsmart in Toronto. I use herpstats as my thermostat because I will be breeding eventually.

Thanks!
