All three are in great condition. They've each only been used a few times and have never fallen off.
I'd like to sell all three as a bundle for shipping purposes but I can break them up if need be. Only asking $45 for all three shipped.
I also have a BMS GoPro power cable that plugs into the cigarette 12v. This is great for filming in the car and not having to rely on your battery life. I used it with my GoPro 3+ for 1/2 mile events. I'll throw this cable in for free if you buy the bundle.
I will cover the shipping cost in the US.
