Random question: Has anyone here used redcart to find merch?

Taobao has been really frustrating for me lately, I keep running into login issues and sometimes can’t even open the listings properly. I’ve been trying to find some Asia-exclusive dolls and merch, but it feels like there are barely any available in the US.

My friend recommended me trying redcart instead, but I’m not sure how common it is yet. They told me they use the image search feature on it to track down limited dolls and merch that are hard to find elsewhere. Has anyone here tried it before?
