I bought an Opus 3100 v2.2 from gearbest and it had one of the dreaded screeching/loud fan. Gearbest sent another under their warranty, but in the meantime I was able to fix the fan on the first Opus.
So now I have two Opus 3100 v2.2, and looking to sell the brand new one I received from Gearbest. I turned it on to confirm it’s v2.2, and charged/discharged a set of AA batteries to confirm that it has a quiet fan and terminates charging properly. Comes with original US power adapter and manual. Asking $25 shipped.
