    I've bought these at BestBuy and at an online store named after a river in Brazil and the ones from BestBuy are built sturdier and you can see the difference just looking at the plug end. Same price or cheaper here and same product. Not sure where other seller is getting their supply but they're not as sturdy as these. Stick with these, you won't go wrong.
