so i was at my local hardware store and i happened across some metal d rings. i then purchased a 1.5,1.75 and a 2" across ring... lets just say when i wear the 2" across i go from normally 8" bpel to a nice comfy 8.5" bpel...plus my head gets super hard and shiny... so why pay 60 or 70 dollars when you can get one for nearly a dollar a piece...just saying and i hope this helps
