Ok well the sucks. I've removed and reinstalled the airflow ring several times and never had this problem. This time I was removing one and after reassembleing the body the coil wouldn't go in. I check and my padding had a gap and cause the ring to add a small bump and take it out of perfect circle. Is there anyway to fix this? Or replacement parts?! I gave my buddy mine and kept his(the one that broke) I can't live without this thing! Love it! Hope you can help!
