I just bought a Spinner and a Protank because my Vamo is still in the mail. I'm running it at 3.7v with a 80/20 juice but don't seem to get a decent throat hit, it's a nice vape but I seem to be missing that little kick in my throat. Is that just the Protank or the volts. I wish I knew what ohms the coil is but there are no indications to let me know. I've consulted the power chart and figured that the coil was 1.8 because most kits come with the 1.8? Don't get me wrong, I absolutly love the filling process of the Protank. No more bruised palms shoving a carto through wonky o-rings.
