Bests & Worsts Reviews from Amazon

They have two different qualities from the same product. I bought one at the beginning that I was totally satisfied with the quality. Around a month later, I ordered another one for my brother. It turned out the new one has a really cheap quality and it doesn't work and have so many issues.My brother noticed that even the call answering button was on the left cord, usually it is on the right cord. So I checked thePanasonic ErgoFit In-Ear Earbuds Headphones with Mic/Controller RP-TCM125-W (White) packaging and it turned out the packaging was different from the first one I got. Even the quality of the packaging was a cheap quality packaging. Also, same products have different barcode numbers and different model numbers. The cheap quality has an instruction paper that was in the packaging and most of it was written in Chinese. I'm totally disappointed since I felt that was clearly deception. I ordered a replacement for the one I got and I got another one with the same good quality. That's where I believe that they are cheating on customers.
