I'll be blunt..stick with Fasttech...they are establish, they have their own forums, discussions...they even allow negative posts about their products as long it's not another vendor link..
Everybody know they are slower than a sloth running the Boston Marathon, but the product will eventually get to you..if not..they do have pretty decent customer service and you'll get your money back..
Please look at ETA ship time, that DOES NOT mean how long it will get to you...if it says 5-7 to days , that means when they will actually drop it off at the post in 5-7 days...I ordered Taifun GS clone, it stated next day, guess what..i had shipping tracking # next day, but now it's up to China post..still waiting...
Good luck, keep asking questions on the forums, I wish I had did back then.
