With the collection I have I just want to buy what a superior T-Stat that is not pron to failure, and that is ACCURATE (accuracy and stable temps are very important to me)

Over the years (been doing that a while) I have tried about every t-stat out there including the ones like zoomed or anything made like it and here what I can conclude

They are not accurate
The temperature varies greatly
They are prone to failure
The wattage does not feed my needs

So is saving $45 worth that to me? NO

Can it work for some sure why not but I have too much to lose to risk it.

And when someone ask for advice I recommend a quality product that I know will not cost that much more but will be reliable and work for years to come.
