issue

Hi everyone. Just picked up my MT09 last week and tweaking it to suit So far i've added a tail tidy, and ordered new adjustable levers as the stock ones aren't great. But i'm now looking for a nice belly pan. I've seen the powerbronze and pyramind one which are ok - but the one I really like is...

seen these on eBay has anyone tried them? I have heard a great deal of controversy regarding wheel alignment and bad adjusters. I personally haven't had an issue but there again I have only adjusted my chain twice. well gonna be doing a few trackdays and hill climbs so any info?
