I think that the well known problems with Coopers have a fair bit to do with where you drive the vehicle.
My boss has them on his D3 and is very happy with them (Perth based and travels mainly only in the southern parts of WA).
We originally had them on company vehicles on a minesite in the Pilbara, and soon got rid of them. Lost count of the number of failures up there - they were complete rubbish in that environment. Just about everything else that we tried up there out-performed the Coopers.
On balance - I wouldn't fit them to any vehicle that I owned (but I am currently running Mickey Thompsons which come from the same factory so I'm told - and am very happy with them).
