Received my 2.1 clone before the weekend and thought I'd put it through a workout prior to posting... It was packaged very nicely and even had spare o-rings, wire, mesh and screws. Pulled it out of the box and my first thought was, damn this thing is heavy. It was almost as heavy, w/ no battery yet, as my Natural in 18350 w/ RSST installed!! Second thought was, damn this thing is small... About an inch smaller than my Natural in 18350 w/ RSST installed!! Impressive and compact. That's what I was looking for. Pulled off the top cap and found it was already set-up w/ dual coils and mesh... Total joke on the setup though! Hotspots for days. I'm not sure what gauge wire it was setup with, nor what was in the spare parts, but found them useless to me so I tossed it right away and rebuilt it w/ 28g... I only set it up single coil for now and will venture to duals in the future. Part of the reason I ordered this was to try out duals. I set it up with a 8 wrap 1.4Ω macro coil and SS mesh. Filled it with juice and was off and running. Vaped really well from the start. I found the flavor was better than my RSST and think that is due to the top cap having a reduced chamber. It was putting out some decent vapor but really not what I was used to with my RSST. I fixed that right away by drilling out the air hole to 1/16"... Didn't change the flavor and now the vapor is on par with the RSST. I may even open it just a little more to 5/32"... Not sure... I chain vaped it for a solid 5 minutes and not one dry hit at all!!! Was even more impressed. This being my first bottom button device has been the biggest learning curve I think i've had with any APV i've owned so far. I can see why some people don't care for them. Being a few days in now, I am getting used to it. The switch seemed to be hanging up at first, but I think it was more of me not pushing it in straight and more of an angle. I am getting a lot better at it now that I figured out to fire it more with my pinky knuckle than the tip on my finger. It doesn't seem to hang up now. Yesterday I experimented with a few setup's and think I have a new winner... 28g 3/4 wrap 1.1Ω w/ 3/32" SS cable/400 SS mesh... I think it actually wicks better than the previous setup I had. It took me a little while to get rid of the hot spots in it, but when I finally did, it was a winner in my book. The only negative I have encountered, it was supposed to come with an 18650 tube and I guess Tobeco didn't send the tubes with Venerable Vaping's order. In talking with Andy, I got the feeling they never even made the tubes and therefore, won't be sending them out... I am thinking of buying an 18500 tube for the real 2.1 just to see if it will fit. The only place I have found them is internationally and with shipping would be a little more than what I paid for what I have... I would like a little more battery life though, so I might pick one up... Here are a few pics of it...
