I picked mine up a couple of years back, run it once every 4-5 months, and was still on the original pad...
If they are wearing out pads that badly, then one (or more) of a few things is occurring.
They are not changing the pads when they should be.
They are snagging the pads on trackwork somewhere that is not quite up to par.
They are not using the right material for the pad.
They are running the CMX constantly, and should not be.
They are using the wrong chemical in the CMX car.
In all the time I have ran it, I have NEVER had that issue.
BTW, even though it retailed for a high amount, I found one cheaper than even the $79 example, and immediately snapped it up at that show. Best thing I got at it that year. (Can't believe it lasted for 45minutes from show open!)
