Vaping one of the Bean's right now. The wood buttons are horrible. Let us know how wood fire button is on Mozaic. It is much smaller than the ThorII and shaped to fit hand. The LG HG2 actually lasts longer than the Ijoy 21700. The LG is a much better battery. The battery caps have to screw all the way in on these. I like it flush with Mod. Thor/II has the best battery cap I have seen. Fully adjustable. The beans do have serial numbers on them Duh. I could not see without my glasses. I have 8 and 24. I do not think he has made very many as it is not his main line of work. He builds furniture. I just hope the button does not break. It feels pretty bad. All wood buttons do. Except for Thor/II. It has the metal stiffening ring around the wood fire button. The ThorII is more worth the $305(first release) than the bean is $500. The ThorII is a real bargain IMO. It is my favorite Mod right now. Most others, even custom I do not like as much. Except Manny's first DPM. Do not know how it "handles" but it is indeed beautiful. Bean's were kind a waste of money IMO. They are very nice and also small but the fire button sucks. Also, I do not like battery cap but pretty much standard on most custom Mods. I am wondering how the fire button is on your Mozaic when you get it. I feel wood buttons, unless reinforced like Thor/II are pretty lousy feeling. The bean's also heat up since they are small. Although I am chain vaping but only at 28.6W and 450F in temp control mode. I can imagine it gets smoking hot at high wattage. It is okay. All of mine are okay. I just prefer the ThorII. The bean's seem to have that hairspray coating like the VA does. They look plenty good without sanding though. I doubt it is poly as it is very dull. Oh well, I recommend them for looks but not for overall performance. Although the Mozaic fire button may be similar. For Manny's sake I hope not. All wood buttons seem to be though. Have several Carlo's Creation just as bad. Actually bean is putting my hand to sleep. So much for ergonomics. YMMV with it obviously. The fit and finish are good at least.
