Yeah, you are absolutely correct on there being a lot out there. Unfortunately, (or fortunately for me), everything seems to cater to the cloud chasers and everything is 22 or 24mm. I just don't get that there aren't more 16-20mm atty's on the market. I am stuck on the O-16's for now and don't think there is anything out there that can give me the outstanding vape I get from them. That's is great for my wallet though.....The interesting thing for me was that at first I was kind of underwhelmed with it as well. Then I switched to the included chuff cap & wow, I was blown away. But if it didn't float your boat then there's no need to keep it, fortunately there are so many great atty's out there! As much as I like new shiny things there's always that part of me that thinks I should just buy another Stumpy. I can't wait for V2.
