Slick is compatible with the GoPro series: 3, 3+, 4, 5, 6, Session, Session5 Black and LCD HERO+.
For the Garmin Virb, the issue is that the camera is too wide so it doesn't fit our gimbal. Same issue with the Xiaomi Yi 4K, this action camera is also too wide for the Slick.
The action camera mount is removable, which gives us the opportunity to release other camera mounts in the future. Let us know in the comments which action camera you would like to see compatible with Slick!
