I would still buy this device. Not because it provides an astounding user experience but just because as far as I can tell it’s competitors also suck:
I care more about having a comfortable nights sleep rather than saving a buck or two at this point and my Nest thermostat is part of the problem. I did figure out how to turn off the wretched “learning” feature of the device - any vendors of so called “artificial intelligence” (AI) products please listen carefully to your customers and make sure that your AI isn’t as irritating stupid at how this product works.
