Just an update...I think everyone who is a moderate to advanced user should have a multimeter (you can get a good one for $15 - $20). I just got some ressurectors, and low and behold the first one I pulled out measured 8ohm. I would have wasted almost 2ml of juice in this thing!! Pulled out another one, measured 1.9 ohm. Ahhh, that's more like it!!
Trust me, I double and triple checked both of them.
It just takes a second to double check the resistance (if there is any...the coil might even be broken!!).
that's all!
probably good practice with any carto before you fill it
