Bests & Worsts Reviews from Amazon

I was really looking forward to this product, and was excited to receive it after reading reviews and comparisons to our current Nest 2nd generation. I went to hook it up, but it would not power on. No problem, I thought.. a quick call to technical support (as I had done with Nest) should get it going. I was instructed to plug in a wire that my nest didn't use. When that didn't work, I called back and got what I would almost have to say is the rudest customer service rep I have dealt with in at least a year. It wasn't enough that they had me crawl into the attic to verify the wire was connected to both sides, but she actually argued with me that it must be broken and asked me to go out and buy a multimeter to test it. After several tries to explain to her it was connected properly, I finally decided to unhook the Ecobee and hook my nest back up. Guess what? It worked perfectly. I did finally go get a multimeter, to find that the wires they were insisting were bad did in-fact carry the 24v current. A few hours after boxing it all back up and processing the return from Amazon, I got a email from support telling me they had marked my issue as solved, so I responded telling them it was not solved and I was returning the item. I then got a reply back from the customer service telling me that my wire was damaged and arguing that the problem was not the thermostat and telling me I should not have rated that I was unsatisfied. I would have probably just replaced the defective one, except their customer service was appalling and rude and killed the entire experience for me.
