This is so stupid. A thermostat has always lasted for so long, now I "have" to buy a new one after they'll inevitably start making the one I have work not as efficient. This a not a start up company, they can afford to keep this going. The only reason I like mine is because I can turn it on from outside or anywhere for that matter. So actually, I dont mind changing because I know there are other companies who can offer the same feature. Other than they they all do the same thing.
