I received my p10 today, and first off, thank you david, it is wonderful. i've been surrounded by clouds of vapor all afternoon. i ordered it with a 510-901 adapter, because i thought that would work with 808 cartos. when i screw the carto onto the adapter, i can draw through it, but once i screw the adapter onto the p10, there is virtually no airflow. did i request the wrong adapter or am i doing something wrong? the adapter doesn't seem to screw in as far as i thought it would, but i don't want to force it. i know that while a 901 atty will work on an 808 battery, an 808 carto won't work on a 901 battery because of airflow issues. but the adapter looks like it should work...it has two air-holes, just as the 808 batteries do. any help would be greatly appreciated.
