I got this as a replacement to my original Samsung Charger which got damaged after a little over a year. According to the Best Buy rep I spoke to, this charger is the original one that comes with the Galaxy S7/S7 Edge (I have the S7 Edge). Basically, while it may be a bit pricey when compared to the 3rd party chargers, this definitely charges well and quick, no matter how many times you charge your phone with it! I've used many knock-off chargers with fast charging, only to have them fast charger for the first few uses and then becoming extremely slow shortly afterwards. Not this one, this one will get always get the job done, and quick. I don't know how so many people have had chargers that blow out or burn up, but I've always taken good care of my electronics, so I've never had those issues. Like I said, a bit pricey, but definitely worth the extra bucks!
