Samsung now selling the Gear 360 camera in U.S. stores5
Samsung's 360 camera can capture 360 degree sphere-shaped stills and record videos in up to 3840 x 1920 resolution. It serves as a high-res camcorder and also lets you capture moments from your travels and other experiences in an interactive and immersive format.
However, the Gear 360 is officially compatible only with Samsung's Galaxy S devices (starting with the Galaxy S6), and the Galaxy Note 5, so bear this in mind if you are interested in it. Also, the camera isn't waterproof (although it is splash-resistant), so using it in and around water isn't recommended.
The Gear 360 usually costs $350, but different retailers may have varying prices.
