I've used the yellow sintered versions before and their longevity has been acceptable, but I've just got through two front and rear sets in two rides! has anybody else had a similar experience and had a response from disco about it.

Yup same happened to me, the front and rear pads got destroyed in one ride!! Will never use them again!!

I only get my pads from them, no problems so far.
Did you bed them in properly?

been using them for over a year with no problems.

I got on OK with them but (flameproof suit on) they're not as good as the superstar ones- at best they lasted about half as long, and didn't have as much power either.
