A friend of mine gave me this mech mod a while back told me it could be worth a pretty decent amount and I haven't used it just been trying to find out more information about it I can't seem to find any records or information on this specific one I have seen some that go by tesla vape lyfe that...

I just put some fused Clapton coils in my new kensei rta but when I fire the coils they go from .25 to .28 ohms. And then when they cool down they go back to .25 I have tightened everything down but they still do it on my mod and ohm reader. Is this ok
