Razer Core X Good Condition - $200 (petaluma)

Connect a Desktop GPU to Boost Your Laptop​ Quick and Easy Setup for Thunderbolt™ 3 Compatible Laptops​ Unrestricted Power for Windows 10 and macOS Users​ This product is in great condition except I kept it in the garage on its face and the front black is a little scratched on the edges but its in perfect working condition.
I can prove that it works if necessary with my RTX SUPER 2080 card, I also bought an RTX 3090 card off of Facebook Marketplace, drove 50 miles and paid $700 and when I got home I was unable to make it work so I bought the Razer Core Chroma which I'm using now to try to get it to work still to avail.
So I'll throw in the probably broken RTX 3090 in for free of just throw it away after someone buys my Razer Core X.
