I picked up a 101D as well. I intended to just leave the RDA in the box and stick an MTL RTA on it for a walkabout mod but when I got it decided to try it out just in case it wasn't as crap as I thought it would be. I just put in an 8 wrap SS316 24ga roundwire build in it and, surprisingly it's not bad at all. If you look inside the top cap there are 2 air directional thingies that point the air directly at both sides of the coil - as long as you look at where the airflow is going to come in (there are small locking tabs) and don't do something dumb like fitting the coil 90 degrees off its intended position its not bad at all - and it actually has a decent juice well for an old school 22mm RDA. It won't be a vaping revelation, but if you have a spool of 24ga its worth trying out. Generally I'm not particularly impressed by older RDAs, but this one isn't shit.
