It's meant to be on your helmet or handlebars recording the, ahem, action.

You won't have to seal a flap on the HDMI port because, unlike the Hero7, there is no HDMI port on the Action-no real-time monitoring from the comfort of your director's chair. The Osmo Action is waterproof up to 36 feet, just be sure you seal the flap that covers the USB-C port and MicroSD card slot before you dive in. DJI wisely included a case and mounting system that mirrors GoPro, which means that many mounts that fit a Hero should also work with the Osmo Action. You probably aren't going to hold this thing anyway. It makes the Osmo Action slightly wider than a GoPro, but it still felt about as comfortable as any tiny rectangular camera can feel. DJI tweaked the basic action camera design enough to squeak in a nice, bright 2.25-inch rear LCD with true 16:9 aspect ratio-no letter-boxed video playback like you'll find in the Hero series. In the hand, the Action isn't an exact clone of a GoPro, but its form factor is similar.

Either way, you can swap screens nearly instantaneously. There are two ways to switch between the Action's dual screens: either use a touch gesture (a two-finger double tap on the rear LCD) or a long press of the Quick Switch button.

That alone will make it a compelling buy for anyone primarily shooting from a stick. The front screen is just large enough that you can tell where you are in the Action's sweeping 145 degree field of view. The front screen is tiny, but it offers a full-color display and it's incredibly handy for selfie videos. The Osmo Action's headlining difference, and what sets it apart from other action cams we've tested, is its bonus 1.4-inch front screen.
