I won't speak for Marty (though I do know of him and deliver to him) but I know a few dozen companies who do manufacturing in China thanks to my job with UPS. Can honestly say you must deal with a lot of "knock off" companies. Those that don't hold the patents but skirt them by going to China and having lower grade crap made and selling below patent holders prices (though their product made at same factory is produced at a higher quality. So not saying you have no insight Kim. Just I have a MUCH wider view from numerous industries and see the different qualities of same product made differently depending on who was ordering (and I mean numerous, everything from outdoor products to POS systems and everything inbetween). Personally watched one company in Gig Harbor start the folding chair market. Yet all the copies are made in same factory at much cheaper/crappier standards. Can say my original chairs from said company have well outlasted the knockoffs and I use one of their chairs DAILY as my lunchtime lounger.
