Hey guys, quick question for anyone that has experience with aftermarket air bags... My X5 is up for sale, but the rear driver bag deflates after a few hours of sitting. I want to replace the bag but I don't necessarily want to spend $130 on an Arnott bag if I can get an aftermarket one for half the price.

Should I bite the bullet and just wait for black friday sales and order arnott or has anyone had positive experiences with aftermarket brands?
