My HR2 helmet is serving me well. It fits comfortable and is snug. It cuts out a lot of noise and is actually quiet compared to the student helmets I have used. Only con is that I sometimes have to strain to hear others talking in the plane.
My biggest irritation was the constantly loosening chin strap - Not loose enough to slip off my chin, but just enough for me to worry about it. I'd have to remove the velcro cover and tighten the chin strap before every jump. The problem went away after I wrapped a packing rubber band over the velcro. Just one adjustment has been needed in about 30 jumps.
