Customer review summary generated by AI, including incentivized reviews.I bought it a few weeks ago when the original mercury thermostat went out. Don't need blue tooth or wi-fi, it is my business where I set my thermostat. It does have programmable, but that is optional so it is good as the original. Installation was simple. Cost was in line. So far happy with it.
