Who did you order from? Please let us know who and we can give you our opinion. 2 week delivery sounds like a China company with a USA office to fool people. If you are suspicious, cancel the order and go with Solventinkjet.com. They only sell Roland OEM caps. Their DX4 dampers are aftermarket, but they have tested out their source. I've never gotten a bad damper from them and I've ordered a lot of them from these guys. Plus they are in Denver.
