Just picked up a SMY260, it is a beast, however when I go to power it off instead of powering down it seams to surge and max out on the rda and burn out the coils or burst into flames if it happened to have cotton. I go to cloud comps and usually use a mechanical but this is my first venture into box mods. I will likely be returning it or exchanging it for another one, but I have to wait till Tuesday to do that so I figured I would pick everyone's brain and see if there is a solution or see if any one has had a similar problem until then.
