nano dry is a flavor GOD! Really amazing, tasty hits. Am sure I'll be doing a little more with my new J-Hook from yeti glass. If you haven't seen his thread yet, check it out.
@VaPeD&CoNfUsEd knows him and turned him on to FC. So far only two small loads through this puppy - but loving it!!!! Will try to get some better pics up soon.
I'd send an IM too if you don't hear back soon. Does sound like your heater has been knocked loose. Earlier models rattled a bit like this after a while because the insides were a bit different, but if yours a year or so old or less, you shouldn't have this issue unless something has been knocked out of place (possibly the retaining clip
@SSVUN~YAH mentioned). Could go on forever with nary another problem with it, but I'd start warming up that backup vape and getting her ready to ship.
Just to reiterate what others have said, if you like the MFLB the nano will knock your socks off! It's not just the volume or density of vapor - which are both much better even with MFLB on PA - but the flavor is in a whole different league. It's kind of like asking a major league baseball player is it worth the feeling you get hitting a fastball over the fence.... I have a whiffle ball and plastic bat.
Also, some discussion above about solo being a perfect mate. I guess it kind of is, and I still use my solo regularly. But, IMO the perfect pairing is a nano and a vapman. With vapman you need a butane jet lighter, but seems so similar to the nano in so many ways. Much wood, simple, very efficient, can deliver small tasty or huge cloudy hits, very versatile. Really nothing too wrong with the solo - but vapman is another keeper that will always be in m vaping arsenal. Now going try it out on this new J-hook!
