Both Sessions are 1 and a half inch cubes that have tiny black and white screens on top that you interact with by pressing either 1 of the buttons found on the top or back of the device. Both Sessions come included with a housing, usb cable, and two mounting surfaces so you can attach your GoPro. One is Flat while the other is curved. Both of the cameras have built in batteries that will last you between 30 minutes to 2 hours depending on your capture settings, if you have wifi or bluetooth on, or if you're using the voice control feature (more on that in a second).

Both Sessions have a side door that opens up that reveals its connection port and micro SD slot. The Hero Session uses a micro usb port while the Hero5 Session uses a USB type C port. The USB type C Port lets you plug in its cable in either direction and also allows for faster transfer speeds. As long as the side door is closed shut, both Sessions are water proof down to 33 ft under water. Any deeper and you'll need a water proof case. On the front of the camera you will notice there are screws going all around the lens, they're not just there for looks. those screws allow you to replace the lens incase its gets scratched or banged up.
