I have 3 Vision Spinners. I bought the first to pair it with my Kanger Pro tank 3 and loved that combination, so got another identical Pro tank and Vision Spinner as spares.
Of course I used the batteries in rotation, and it wasn't too long before I noticed that one of the voltage adjustments on the bottom of the battery seemed very loose and would not stay in place. Having reason to believe it might have taken a fall to the floor, I replaced it.
Much to my dismay, within a few days one of the other batteries exhibited the same problem; and I know for certain that that battery had not suffered any shocks.
My question is, is this a known issue with the Vision Spinner? have I maybe purchased some counterfeit junk? I did get them quite inexpensively at the local tobacconist; I happen to know he is in business to turn a buck....
Thanks y'all!
Cheers
James
