Doesn't fast charge S7 edge - Finicky after 5 months use

Update: I've lowered the rating from 3 to 2 stars. After 5 months of use the chargers no longer remain in place in the phone's charging port. You have to now wiggle them just right and set the phone down gently to keep the charge going. This product brands itself as an 'adaptive fast charger' for the S7 edge, but this is not the case when I charge mine. It works as a standard charger. I also have an S6 edge+, this product is able to fast charge that model. One small detail I'll mention as well is the micro USB connector has a small amount of extra space between the phone and the plastic part of the charger. Not a big issue, as the connection is secure, but it's worth mentioning. For the positives, the braided cable is nice, and 5 feet as advertised. It still charges just fine, albeit slower than I'd expected.
