They should last if you take care of them. Take extra precaution when removing the pads from your BP. Separation of the backing is inevitable, but you can make it last a long time with proper procedures. This is also why I like my 7.5" LC pads, the velcro backing is pretty much molded into the pad, making it impossible to seperate.... a few of my pads are 2+ years old... still going strong.
