Anywhere from 7-21 days.... I usually get them in 10-11 days.... I tell ya I recently got a bad cylinder from them.... they asked for pics and I sent some....I never had to be rude or contact ebay, they sent me a knew cylinder.... I was more than pleased with their customer service....coming from China I was really surprised it all went so smooth!!!!!!
So yes you will get your parts, may take more than a week, but they WILL come.... I had my worries the first time I ordered from them too, but I have no problems with roughly 6 orders from them....
