As a hot tub technician I replace these balboa style hi limit/temp sensor all the time. However this is my first time using a off brand but they are still holding good in a customer's tub 3 months later. Will try to update at a year. So far they are a much cheaper alternative to balboa parts.

I thought these were inaccurate at first but it was something else. These are good.
