Review on Motorad 678 221 Integrated Controlled Thermostat by Sean Baller

Total nonsense. I bought it in June 2016 and installed it after it arrived and it just broke and poured coolant out of a seam. Including temperature. The sensor was rubbish, used the original for good results. Just ordered as I was in a bind. Next time I will be authentic. Edit: There was no seam. It actually broke near the seam, about three inches long. Explains why he lost coolant so quickly. Today (01/24/17) I installed the original mini thermostat, no problems.
