love the vamo, but have to say their 510 threading is the worst ive seen on a mod thusfar. i just threw a brand new stainless v2 into the drawer because the threads .....ed up first thing. i put a brand new protank on it (ORDERED IT WITH THE VAMO, BOTH NEW) slapped a battery in it, vaped for about 10 min total, bumped it (didnt drop it or slam it, bumped it on my leg) and the tank popped right off and wouldnt screw back on at all. all every tank ive got now does is just spin in the 510, cant catch a thread. cant catch a thread on a brand new air flow regulator either. same time of ..... over time with the evics also. if you change tanks often the chrome plated brass threads in this junk will wear out fast. id pay an extra 20 bucks a pop on mods just to have one with actual stainless steel threads.
ive noticed that it seems every mod ive gotten sofar that the 510 threads are crappy.quite some time ago i started buying air flow regulators and putting them on my mods when new before even threading a tank on. i just happened to not have one with the new vamo. my bad. i wish these manufactures would build a quality product.
