After a lot of research, I settled on the Ammit 25 to begin my subohm flavor chasing and MYVPRO had the best price I could find. I ordered 2 and the order was shipped promptly and arrived quickly with a freebie atty stand included! After the usual newbie mistakes with wicking I got the first one going and was ecstatic about the flavor on my SS316L 26AWG 6 wrap 3.5mm coil @ 28W. Unfortunately when I built the second one and juiced it up a huge mess ensued. After a couple more attempts I was about to conclude I had a bad atty. I then found online the fix for massive leaking around the airflow control ring: tighten the 510 screw while holding the airflow ring until build deck rotates to the stop. Unfortunately for me, I didn't realize that the main screw is covered by a small and very delicate cover screw and I promptly broke the threads of the cap screw off into the main screw. Chastened, I removed the two screws from the first Ammit 25 after I vaped it dry and rebuilt the leaking one, but tightening only the main screw. Worked like a charm - no leaks at all! Called MVPro and explained to John what I'd done and he shipped out a new screw before we finished the call!! MVPro has made an old f*rt very happy! John's professionalism, courtesy and efficiency has made me a customer for life! Thanks John!!
