It took me an additional 2-3 hour to complete the process because it would not work until I finished registering it.

This one has sapped four hours of my life.

I spent a total of 4 hours on the phone with tech support, the first 2 hours were painful and unproductive, until I called back in to get a different support rep

After a fruitless hour on the phone with an Ecobee tech, I decided to disable the voice system, disconnect Amazon and rely on the smart phone app for my thermostat settings.

This is a crappy product, service is terrible spending hours on hold waiting for tech support, you bait and switch by telling me I could get a large rebate only to tell me that I can't, and I have to stand in front of it and yell at it to get Alexa to work!TERRIBLE in ALL respects!

Worst support on the planet .3 hours and 6 minutes on hold waiting for tech support ,no one ever answered
