SuperbPlease see pictures with test results.I wanted to test this and compare it with the charger that arrived with my Samsung S7 Edge.. They look almost identical, the only difference is the country of origin and this product seems to have some sort of ring to it if its tapped by the finger, suggesting that there is some sort of coil or spring inside, my original phone did not have that, this product also runs hot, it is at least 10 degrees F hotter than the original charger, and at home point it got to over 100 degrees F.However, when it comes to performance, this charger is perfect. It averaged 6.35 Watts while charging my phone vs my original charger which averaged 6.1 Watts. Also I tested a full charge from 5% to 100% and it achieved it in 90 minutes, this is on par if not better than the original charger that arrived with my phone.People seem to differ on whether this is a genuine charger or not, I don't know for sure but it certainly looks so, it seems that it is genuine but the OEM is a different company than what it was a couple of years ago. Either way, for this price this charger is a no brainer, I definitely recommend.
