Bought this to record an epic 60 mile bike ride from Norwich to Ipswich. 5 miles down the road, and one of the bolts fixing the bracket to the arm had fallen off, and the other was about to drop out. Quickly pulled in, and removed the entire thing so I could repair it when I got home. It's a reasonably solid build otherwise, very light and fits perfectly. I've now firmly screwed the remaining bolt back in, and got a replacement for the one that fell out somewhere near Poringland. A drop of loctite on the holes, and I'm sure we're all good again. Try another session on the bike next weekend, but I'll be keeping my eye on it.
