Comfortably the fastest rugged phone we've tested, the AGM X3 is also better-looking than most - but a little less tough as a result. It offers a decent middle-ground option for those who need something more durable than the average smartphone, but without entirely sacrificing performance and design. Do keep in mind that you can now find the 2018 flagships with which this phone competes for less money - as rugged phones go, the AGM X3 is still within the realms of affordability but it is not cheap.
