So I've been using Amazon for years, and only had a bad experience once. I always used to use Anker products, especially their screen protectors that were cheap and worked well enough.

I ordered the exact same listing maybe 4 or 5 times (at the top it would say 'You ordered this item on XX.XX.XXXX) and the sixth time I ordered it, what turned up wasn't Anker at all, and wasnt' even pretending to be. The pack was completely different and this was from a store listed as 'Anker'.

Of course, Amazon refunded and sent the correct item but it does happen.
