I only saw the PB test.From what I can remember,it was fairly efficient.They did an impact test,distortion etc.and I think they did a metal structure test.I can't remember any more!.
With regards to China copying everything,it doesn't necessarily mean it's all crap.I seem to remember we said the same things about Japanese stuff.
Surely someone in China wants to do something properly!
Going back to the wheels,one of the ebay sellers claims to make(or did) OE wheels for Triumph-if so,presumably they had some quality control.
Whilst I appear to be approving these wheels,it doesn't necessarily mean I would buy them!.Unless I was specifically racing in a Superstock class I would save up for a nice set of forged wheels for dry and use the OE wheels for wets.
I bought a pattern clock bracket from China which,apart from the supplied rubber grommets,was perfect(although,to be fair,the composition could be suspect-then again,try welding an OE one!).As Bananaman said,the screens are first-class.
And as was previously mentioned,everything seems to be made in China these days.
