There's a deal right now at amazon on them. You can get them for around 6 bucks per. https://bgr.com/2020/02/14/amazon-deals-of-the-day-on-feb-14/

I'm just not sure about them though. I guess they work with Google assistant - I'm just not sure how i'd use them. I guess I could have the lamp in the front room hooked up to one, and then I could turn it on and off with Google?

If YOU use them, how do you?
