these controllers don't last long i had the pro+ black one for PC use it only lasted a year. one day it just wouldn't charge no matter what i did. threw it in the garbage where it belongs they are cheaply Chinese made shit.
I've had my SF30Pro for about three years with no issues whatsoever. Great controller, especially for indie and 2D games. Only reason it's been shelved for now is that I bought a Pro 2.
I am owner of several controllers, NES30, SN30 SFC30 and a SN30 Pro+, and a Retro Receiver & Adapter GBros, they are very nice controllers and adapters, they works very nice, are very easy to use, they look great and the workmanship is outstanding. the only problem I have with my SN30 Pro+ is what the maximum value for axis is get when the stick is about the 70% of the travel, that is a firmware problem and occurs on all modes so only 8Bitdo can repair it but they hasn't been any help.
hahahaha I'm half way through a bag off my Volcano and my tolerance is way down because I haven't been smoking much lately, so I was a little slow to catch that that was what your angle was
