To clarify, the ring moves just as it did before it stopped working, it doesn't stick; there's just no response on-screen when it is manipulated.
I bought it from the classifieds from an individual who purchased it from a co-op. He said he had it for a few months and used it very little. It STARTED acting up about a week and a half after I got it from him. At THAT time, I did a cleaning with a q-tip and rubbing alcohol to ensure it was not something gunking up the ring.
It did not start sticking weeks before. I have not had it for a while. It didn't stop working all-together, the selector ring alone stopped working. I did try cleaning and it did not help. I have been very careful not to drop the
device and it was in good working order before I received it so, as biased as I may be, I don't see how it could be user error. It's no secret that the Evic isn't of the highest build quality when compared to similar devices. I understand the impulse to defend an APV you may be a fan of but I'd appreciate advice if you have any instead of snarky back-handedness because you missed your nap today.
I would say this problem is more akin to buying a used car and having the tires shred out of nowhere after they had been working perfectly for a couple weeks.
At least I still have a functioning battery charger and ohm meter for my more reliable mechanical devices.
