The Bear quivers have some vibration issues that cause some noise.That can be fixed in a few minutes.I used them for many,many years.The lower spring arm will vibrate off the bow after several shots,like when practicing.That can be fixed with a velcro strap.
Arrows eventually slide down the grippers and you find yourself constantly pushing them back up in the hood,even with 11/32" shafts.If you don't,you get noise from loose broadheads in the hood.
I finally had to give them up.There are better and lighter quivers made now.The EFA can't be beat for lightness.
