I ordered an "oem" lens cover for my LG G4. They have a video highlighting the differences between that version and the inferior "custom" version, which has a plastic lens and no metal screwhole reinforcements, and when I got the product, it was clearly the latter. I duly contacted them and explained the situation, and after a number of email exchanges with Chen, he insisted that I take a photo of it and send it to them, which I promptly did. Now they don't even respond to my emails. Consequently, I was forced to dispute their charge on my credit card, and now I have to shop for a more reputable source. I've already wasted more time on this than the product is worth, and I would advise anyone to stay away from this shady company.
