This isn't a post to bag on Notcigs or the Buzz Pro but, I have to report back on my recent experiences. I have been enjoying and using my green buzz pro for about a month now. My curiosity and dilemma started after I bought my wife a BP. The issues vs my wifes BP: 1. softer/squishier button feel and response 2. less impressive vaping and inconsistent hits After removing my top cap I couldn't help but notice how loose the top screw was. And, the button was slightly broken from its initial adhesive. To correct these issues I manipulated the pcb board into a slightly better position, superglued the button into the perfect triggering position, and tightened up the top cap screw (left a slight amount of play on the bottom of the top cap wire screw to allow the wire to rotate). The results: Perfection. Button effectiveness was good before and without issue but now that it is better secured and free of the walls it has a firmer feel and more solid "click". Tightening the top screw resulted in a stronger vape.... I cant help but think the loose connection was impacting the circuitry's ability to produce a good vape. I'm now happier with the performance of my buzz and I'm vaping on a 3 ohm carto below the yellow mark. (before I was half way between the yellow and red mark.) Ian I don't believe this was an issue of assembly or quality control. I think it was more likely just preventative maintenance. The screw holding the wire to the top cap had worked loose over time and it's very possible that I had jammed the button breaking it loose from it's adhesive.
