Hiya GotVapers! I recently bought an 18360 Gripper from GV along with the 510 extension. I also got some more Stallion cartos thinking they would be a perfect match for it. Having read and heeded the warnings about not over tightening the carto so as not to strip the threads I eased in my first carto and pressed the button. No fire! So I ease it in a bit more. No fire. So I'm thinking bad battery or bad unit. I try a fresh battery. No fire. After doing a Curley (3 Stooges) face slap and barking at the unit a couple of times, I pulled out the carto and inserted the extension with the carto on top. Giant clouds of wonderous vapor! Ahhh! So...Is there an incompatibility problem here? If so, what cartos will work without the extension? I'd sure love to know what you guys and gals have found to work. Thanks for reading. vape ON..
