Bests & Worsts Reviews from Amazon

I have been looking at Nest for a while now, my neighbor down the road installed two in his house and he is pretty happy with it, he did replace his ancient mechanical thermostats so a big improvement I would imagine. I have a two level family home with two cooling/heating zones. We have a conventional HVAC so it has all the required wires i.e.W, C, Rc, G and Y to connect to the Nest unit. I started replacing one of my existing Honeywell electronic touch screen controller (non WiFi) which has been working great for about 7 years downstairs, so the upgrade is based on my curiosity and affinity for new electronic gadgets. Installing took 5 minutes, pulled of the old unit, make sure you turn off both the Heat and AC breakers, I connected the wires to the nest panel, plugged in the face and turned back the power. I was welcomed by a nice bright round color display that guided me through setup including connecting my home WiFi. WiFi connection no issue, it also did an update. The iPhone app works great as well, very happy thus far The unit does most of the basics, activate the AC and shut it off so no problem there. Display is nice and bright, navigating through the menu is easy and simple. The 'wake up" feature is great, as you approach it the display lights up and will stay illuminated while you stand in from of it, if will fade and go black a few seconds as after you moved away. Now come my gripes about the 3rd generation and most expensive SMART Learning Thermostat. 1st is the way it displays temperature, there have been many complaints about this going back to 2013 on the Nest Forums...and you have guessed right ! The target temperature is displayed in big two inch font in the center whereas the ACTUAL room temperature in small 1/4" font on the outer ring, after two years and hundreds of customer complaints and a 3rd generation unit revision it still has not been fixed. When i placed the order I unfortunately did not pick that up reading the handful of reviews here. Huge issue for me and I'm sure a lot of Nest users. To quote previous analogies, it is like an alarm clock that displays the time the alarm will wake you and not the actual time during the day??, enough said. Nest, you need to address this !! Now the temperature drift issue ... when you set the target to say 75 F and say the actual is 78 F, the Nest will activate the AC... to be expected right, however the Nest will not act and switch of the AC until the actual is 1-2 degrees below the target. Similarly the Nest will wait for the actual to drift 1-2 degrees above target before it will activate the AC, that is a 2-4 degree range which is a huge tolerance. Also when there is up to a 3 degree difference between actual and target the actual temperature will NOT be displays on the outer dial, I spend and hour with Nest support and they say it is normal, if I want to see the actual i have to move the dial so that the actual and target is more than 3 degrees apart, only the will the actual temperature be displayed, another huge oversight. The above are two very big user interface and operational effectiveness issues in my mind. I have ordered the latest Honeywell WiFi controller and will install upstairs to compare against the nest, from the reviews I have read i will probably send the Nest back and settle with two Honeywell, time will tell.
