Hey guys. Your always helpful so just thought id ask. I'v had the lemo drop delivered today. Had It for 3.5 hours and finished a tank. I vape a lot so that's not a worry. Its great. No leaks, no flooding, mtl hits great, lung hits no guzzling juice. However I had half a tank left 30 min ago. Now I have to refill. The second half of juice seemed to disappear. Has anybody else had this happen? The chimney bit is the same size the whole way down. Anybody know why?
