I don’t know much about Mooxi, but it seems like they work with World Minifigs (AKA WM). That’s a good sign for me as WM has been producing good-quality molds recently.
I think that even collectors who don’t buy third-party Minifigures might want to check out these accessories as Lego doesn’t have them.
Right now though, I don’t see a lot of stores selling them yet. But I’m sure that given time, these will be more readily available.
