Can I do the same for like EcoBee?

I bought them a year ago and today they showed me an ad ON MY THERMOSTAT.

If you bought from a big-box retailer and you’re considering ditching ecobee because of this, you should try to return them. Even if you’re outside the return policy, if you’re pleasant to the customer service staff they might be able to help you.

Amazon reviews are essentially meaningless at this point, the important un-fakeable stat is return rates. Brands care, and retailers track it and will drop products with high return rates.
