Negative Positive
Title: Short Lifespan
Review: I purchased three of these regulators for my larger terrariums, and all three failed within two years, just out of warranty.These would be beneficial if A) They had an appropriate lifespan, and B) If they were made such that you could choose a temperature range for the default setting. When choosing your preferred temperature, one has to guess how hot to set it and modify with time. If it were able to show a range (70 - 75 degrees, etc.) as opposed to the cool-to-warm color gradient on the dial, I think it would be much more useful. All three failed within two years, and I shan't be replacing them.
