Had my mini fogger for about a week now (got it for like $30 on ebay). Have to say, I am completely unimpressed. I can not get this thing to wick right, I feel like I've tried everything; long, short, fat, thin, rayon, cotton, wetting and trimming the wicks before and/or after the chimney is on, nothing seems to work. I get about 2-5 decent hits then I get a nasty bunt taste, reminds me of the scorched rubber taste I would some get on old evod clearos. Those big deep juice channels looked good in theory to me, but in this unit it just doesn't see to work. Looking at it closely, I notice that when you screw the bottom part of the chimney on and install the o-ring that holds the glass piece in place the juice channels are basically completely covered, which I think is probably the root of the problem. Even though the juice channels on my lemo aren't as wide and deep as the mini fogger, when you put the chimney on you can still see the bottom part of the channel where the juice flows through. Also, the o-rings holding the glass tank in place on the lemo are flat and on the fogger they are raised. Not only does this block up the channels like I mentioned before, it doesn't create as good of a seal as the flat rings. The air flow control is also pretty crappy. Very hard to get the threads to catch evenly and once you have the entire unit put together you really can't adjust it very well. I tried using it with the ring completely removed, but it leaked really bad well I filled it. The top fill port was another feature that looked good in theory but didn't function as I hoped. I always got some sort of leaking from the bottom when I filled this unit, and trying to extract the juice from the port (using a luer lock syringe) was a pain. I just about given up on this thing, it got pretty annoying having to extract my liquid, re-wick it, and re-fill it after just a few hits just to have to repeat the process all over again, I wasted too much of my e-juice and time doing this.
Just wanted to give my thoughts on this unit since there is not a lot of info about it out there. This is only my second rebuildable, so I am still kind of a beginner in that aspect, but I have had close to zero problems with my lemo and the mini fogger has been nothing but problems for me. If you are more experienced when it comes to rebuildables, for the price it may be worth trying out, maybe you'll have better luck than me. If you are still in that beginner stages with rta's like me, I would look elsewhere.
