Ordered this for my sister and it turns out she already has one. and I am way past the return period. These retail for $249 on Amazon and ~$200-225 on eBay. Asking $175.
It's the latest/3rd gen unit and is brand new in box, sealed in retail packaging. I have the same unit in my condo and it cut my gas bill by 40%. Plays nice with Alexa and Google Home. Easily pays for itself.
