GoBUDi Extension Pole Set Compatible With All Gopro Hero Cameras - 3 Extensions And Bolts

Does what it says on the tin!

They are 3 different size aluminum tubes with plastic GoPro mounts at their ends. It will give a nice little extension to your camera and the 3 different size is a bonus, but I would not trust my camera on this while riding my bike. The connection between the aluminum tube and the plastic mount feels like it will come apart in case of a stronger shake, what you usually have on motorbikes or mountain bikes. I would not recommend it for action sports, but definitely a good buy if you want to attach it to something less action packed as overall it's lightweight and well made, just the joints don't feel secure enough to withstand rough terrains.
