For the price I shouldn't complain but was hoping for bearings that spin a bit more freely than these. There aren't any loops or anything, they're just not very loose. I think of roller skate bearings spinning forever, but they don't. I bought these to use with a homemade GoPro camera steadicam and the idea was to place it in the grip so the camera can pan easily like you see on professional gimbals. These bearings allow the camera to rotate smoothly, but as soon as you stop pressing on it, it just stops. I will buy other bearings that can do that.
