Order 100 screens a month from here, and have been for 4 or 5 months now. Had a few defective ones but by far the highest quality iPhone 4 screens I've seen. My advice is to place a large order to take advantage of the higher discounts. When I order 60 at a time I max out the discount so I plan ahead and always order at the beginning of each month. Love this company and its obvious these guys know what they're doing - selling quality products at low prices with no BS and upselling like a lot of my other suppliers have been doing lately.
