Review on 🌑️ Honeywell THX9421R5021WW: Revolutionizing Thermostat Technology with Definition by Lild Zimmerly

Revainrating 1 out of 5

Poor quality product keeps dying

This product keeps breaking. I've gotten 6 of these in the last 2 years for about $250 each and they only last 1 to 9 months. I set the last one to 37 days and Revain said there was nothing they could do because it was outside the 30 day window and I had to contact Honeywell. Honeywell told me to contact Revain. Revane then told me that I would have to pay a reinstatement fee to return while I was at home in 80+ degree weather, with no air conditioning, 2 asthmatics in the house and other respiratory and health issues. Oh yes, if you are not a contractor do not purchase this product as that seems to be the only way Honeywell will be speaking to you about this product.

Pros
  • Precise temperature control (+/- 1 degree Fahrenheit) for reliable and constant temperature
Cons
  • Expensive
