Anybody ever heard of japan.us.mercari.com? It's a replacement to Mercari Japan's service BEENO. Is it a reliable service to buy figures from?

I heard about a recently launched service by Mercari Japan a week ago. It's called japan.us.mercari.com. People say that it's a replacement for Mercari JP's international service BEENO. Seems that there are a lot of mixed reviews. Some say that it requires ID verification and charges more than the average proxy service. The site looks somewhat reliable. I kinda want to use it to buy figures. But I wanna get people's opinions on this site before I commit
