I love mine !
I think the Herpstat is definitely one of the best. The only thing I do not like about it is the programming. Its the only one I get the book out for when I need to change any settings, LOL.
But that isn't really a big deal at all.
You did good. This purchase is what keeps everything you own safe. Just make sure your probes will be seated correctly and check every now and then that the probes are still in place, so that the thermostat can do its job correctly.
