I use a Herpstat and VE-200. I haven't had any issues with them and so far, they're working out pretty well. The store suggested that I get this:

and I noticed that it does have a safety feature where it would shut off if it hits 110 degrees.

That makes me wonder, how high would the Herpstat go before shutting off?
