I have had oneof these chargers for quite a while. Bought it because of it's ability to charge 18350s without spacers, and also because of the 4 bays.
I was not aware of some of the other capabilities that Busardo covers in the review. I guess I got more than I bargained for. LOL
I do have one bay that gets a little weird at times. It will indicate full charge (all 3 lights lit) even though there is nothing in that bay. I just unplug the charger, plug it back in, and all is well.
