I need to replace my thermostat and I see a lot of negative reviews for "Failsafe" units--sold my Moss and many others--which are designed to fail in the open mode. What is the collective experience with these?

IMO, there’s a trade off. The original bellows types have a larger opening so more water flows through them when compared to some of the failsafe ones. Were the bellows a big problem in the Healeys when they were new, I don’t recall any problems with them then.
