I've just recieved this through the post, selected the normal postage ordered on the friday and it arrived on the monday, so that put a smile on my face straight away. Opened it up and its a nice little piece of kit, everything nice and accesable, nice to have the lense cap, tripod mount, extra screw, and little spanner to tighten the screw also. The frame itself feels a tad delicate but that was always going to be the case given that it needs to be flexible to get the GoPro mounted inside it. I've not used an official GoPro mount so can't comment on how this one compares to it, but the price of the official one put me off instantly.
In short, I'd recommend this frame to anyone looking to not have their pants pulled down by the price of the official GoPro mount :-)
