Hey!
I currently am using a Samsung Galaxy S7 Edge with the Gear S2 and its wonderful. The phone is extremely quick; apps load up nice and fast with minimal bugs, every game works perfect, and the camera is fantastic and takes super fast pictures. S7 Edge with Otterbox will not break! The Gear S2 is great for on the go anything, especially if you are using a bluetooth headset. Most technicians I see around here (DC, Maryland, Virginia) are using a bluetooth headset so most would benefit from a smart watch believe it or not! :) Sorry for getting off topic a little bit, but I would strongly recommend the Samsung S7 Edge to any tech out there with an upgrade.
