Great thanks I did this and my new PR101 that was hard to draw is much better.. interesting.. since it was new.. But it worked..there are two small vent holes on opposite sides of the battery threads and every so often you need to take a sewing needle and poke around in them to keep them clear and clean - you'll recognize when you need to do this because your cig draw will become harder-it should be real clear and easy.
YEAH!!
thanks so much
