I just put in the octuple (or howerever it is spelled) coil last night that goes from 50-260w (recommended at 120-180). When I vape it at 110 after about 4 puffs the bottom starts to get hot and if I take a good hit off of 140w or higher it gets hot after one hit. Has anyone else experienced this? The other coil that goes from 90-150 I could vape at 120 back to back without it getting hot at all.
