This has been hashed many times and it comes down to one thing,IMO, how much pressure you use. I have some pads that have lasted 15-20 balls, not that much pressure and they are the 360-500 range. The 180's won't last as long, 2000 and 4000's last a long time, again, depending on the pressure you apply.
One thing I do that, I think, makes them last longer, when cleaning them after use, I use a nail brush to get any particles out of the 'weave'. Not sure if this really helps, but I think it does so I'll continue to do it that way.
