"Brains" of Prime Wire smart outlets?

I was tempted to pick up a 3 pack of smart outlets by Prime at Costco. The product information is pretty thin, but I am wondering if I could get them to work with HA? Has anyone opened one up? Are they built with the ESP8266 and so flashable with Tasmota?

Can’t say for sure, but those outlets look exactly like the ones I just bought branded Globe, which were just Tuya devices. Was able to use Tuya-convert to re-flash them. From the link you posted it looks like the Prime are the same product, and thus Tuya.
