Our air conditioner installer recommended getting this model as he thought it was the best on the market. It is very easy to use and has many options. Had a question, called customer support, and the service was very helpful and friendly. Would definitely purchase again.
First unit purchased had a broken connector where the wire pushes in. Second one received worked fine. Phone number for tech support is out of service but once I spoke with my hvac tech I figured it out. Pretty simple to use and app seems to be working fine.
I already had one of these, which is why I got a second one. It is so easy to use and read, and sends you a monthly account of your heating, A/C use, as well as average high/low temps for the current year and last.
