Thanks guys, I’ve ordered a set of the genuine GoPro pads as shown by DanW.
Don’t get me wrong here. The lights are great, the batteries seem nicely put together and the remote switch is simply awesome.
Just a shame that the fitting kit supplied doesn’t quite work (or at least is not the same standard as the lights). After spending £335 (XS and a second battery) you’d expect to have all the parts you need.
I guess the heads-up to people considering the lights is to buy the mounts suggested above and some decent quality velcro straps from elsewhere at the same time (if you plan on frame mounting a battery). That way you’ll be able to get up and running immediately.
