Had checked out the Ismoka Mega BCC for a two weeks.. I like the way the coil fits into the base and seems this system minimizes leaking on the battery. Also like the fact you can change out the tips.. Kanger T3s seems to be a great vape but does like to leak a bit and likes to slurp a bit when stored upright. Also the Ismoka seemed to do better than the Kanger in elevation changes and pressure changes. Which is important when living a mile high and traveling. All Kangers BCCs would leak in the stem and would be like drinking from a straw when taking a draw when traveling at different elevations... Its not like flying in a plane.. Pressure is constant when traveling by plane...I do like the fact that Kanger finally went to one type BCC coil. But Ill take the Ismoka Mega... Sorry Kanger.
