Thanks for the heads-up. I tried the adapter with a kanger MT3 after that, there's no problems with it or the AGA-T+ so the pin seems ok.Some of the 510-eGo adapters have pushed the contact pin down on the Vamo. Please be careful when you use them. You might want to look at this thread: http://www.e-cigarette-forum.com/forum/vamo/375871-vamo-ohm-error-fix.html
