I have the same one that I bought as part of a large pack of mounts from chinky ebay. I would not pay high prices for mounts as I suspect that they are all made in the same chinky factory.
Not so sure about the "chinky ebay" stuff. I have broken two such items, one on the Multi and the other on the KLX and the GoPro was on a short mounting so no real mechanical stress. I decided to buy a genuine Go-Pro mount as Halfords had an extra 10% off on Christmas Day so bargain, so cost was less than the two from ebay that broke. Furthermore, I modified a cheapo mount from ebay by using the claw that grabs many tube diameters and I used epoxy to secure a camera mount bolt (1/4 inch UNC-20) and hey presto I have a mount for all occasions now.
