I had a Vamo V5 which broke so I bought a replacement V5 which it turns out I think to be Chinese replica because it's quite different. The new one in the picture is on the left and the old on the right. The tank on the far right used to fit the old one fine, but as you can see from the pic, the contact on the new one is deeper in the threading so unfortunately the tank screws in but doesn't make contact.
Anyone got any ideas on how to resolve this?
Thanks!
