Quite a few years back I bought a Dubow which had a Kwik, it wasn't a great experience as when I got the jacket from the ebay seller it was in poor condition, one arm was separated from the shoulder seam and there were small holes in the leather, the seller wasn't willing to take it back (I've learnt alot since then about eBay rules!) but offered to pay for repair costs so off it went to Aero; despite the Kwik zip being sound or so I thought it came back to me with a replacement Talon as Aero said the Kwik was faulty(?); decided to sell it and cut my losses, decided it was a jinxed jacket!
