It seems to be a Chinese brand, Amazon reviews of their cameras appear mixed. Nothing on their wifi doorbell, probably d/t being a new release.
If you're looking for an alternative to Ring doorbell, then I would highly recommend Skybell. I think they were the first (or one of very early) makers of wifi doorbells. They're not cheap but unlike some other smartbell manufacturers, they don't charge monthly/yearly fees. You get unlimited firmware updates & cloud storage for life, which might explain the high upfront cost. Had my Skybell for nearly a decade now, very happy with it:

Yes you can have multiple Skybell units installed in a home, the app lets you rename them if req'd.

Bought the 1st gen Skybell from Skybell USA directly many years ago. A few years ago I upgraded to the Skybell HD Trim and bought this from Amazon USA - I don't think Skybell USA offer int'l shipping anymore. Never had any problems with using the Skybell (any version) in UK, cloud usage works perfectly
