Buying direct from China is risky, BUT.....
I would have given three star because I think you need to be extremely cautious when buying, as an individual, directly from any Chinese based vendor. Examples of being sent an inferior product, being saddled with additional customs duty costs, even vanished items in delivery, and then shockingly bad customer service, if the Chinese company do any of these, you have no one to turn to, so be aware. But I twice ordered low cost phone replacement parts from this vendor, and twice did not have any issues. Both times I paid a reasonably small amount of money for a replacement screen with digitiser. About £6 shipping. Both times I received the items well packaged. I didnt get hit with import duty. And I received a working product which was of good standard. Once fitted both phones worked again wonderfully and I felt great having fixed them myself for £20 each. I think if you have £500 to spend directly with any Chinese vendor, paypal or no paypal, you have to expect to lose £500. If you want a £15 replacement phone screen to fit yourself, I think from my experience this is a good vendor.
