The Revo Curved Adhesive Mount for GoPro two pack allows you to affix your camera to smooth, rounded surfaces and are ideal for helmet-mounting. The mounts accept the GoPro Quick Release Buckle (available separately), and can be used with any HERO model up to and including the HERO4. The adhesive pads form a semi-permanent attachment that can be removed later on using a hair dryer.
This is exactly what I needed without any extras: Curved helmet mounts for our GoPro. We have these mostly on our winter ski helmets, but also want one on the occasional bike helmet - and we have little use for the other (flat) mounts that typically come with the curved ones - so to have a pair that are specifically curved is great. These fit the clamps and mounts perfectly and the 3M included adhesive tape is just like what you would get direct from GoPro. Huge win, and at the right price too!
it works gr8 on my helmet (tip) damp the place ur putting it on b4 and its good to go its awesome:)
