anybody tried these wheel spacers

Ive just changed the bearings on the 450 and found lots of crap inside the hub, the spacers are well ringed and i can only assume the rings on the spacers are letting the shit past the seal which in turn trashed the bearings.So i found these spacers, as mine were ferked anyway, they have an extra ring to make the seal a better fit.
