It's not easy to find legitimate Samsung replacement accessories online because ****, ****** and others allow people to sell bootleg knock offs under the Samsung name, so people buy them expecting the real thing, then they either don't work, stop working after a few days or end up even ruining their phones. It's a shame that other sites allow people to sell cheap Chinese knock offs that don't work. Fortunately, these data cables are the real deal.
The data cables in this pack are even higher quality than the one that came with my Galaxy Note 3. They're much stiffer (which should make them more durable) and they charge my phone just as quickly as the original. Having two is great because I leave one at my desk at work and the other at home. I highly recommend these.
