Reddit mentions of MECO WiFi Repeater (red)

I had this problem with my left stick and fixed my vita on Saturday by purchasing a new stick and replacing the drifting one. It's only been a few days, but the drifting went away. I also had a vita slim.

I bought this (these say used, can't remember if mine was):

and followed these guides to replace it:

Hope this helps! I already had many of the tools from a repair I did on my android phone a few years back, but all you'll need is a spudger (to separate the casing), and an electronics screwdriver set like this one https://www.amazon.com/dp/B01MR79LNT?psc=1. No electrical tape or soldering required.
