Yes, the clogging was very frequent, which I thought was odd since the chiller, which came with my rig never clogged. After a couple of months or so, I realized what was happening. The piece perspires and leave a small amount of water inside.
Just blow a few times through the male end prior to placing it back in the freezer to eliminate the water. No problems thereafter at all with clogging. Cools the smoke and makes for a much nicer experience.
