A friend and I have both had these fail - mine after 11 months of ownership with light use (pun intended). They are lovely but agree with everyone here, the mount is rubbish.
Also, I didn't receive a reply from either the UK or European fabric email addresses.
A shout out for ProBikeKit who are refunding the purchase price.
The fabric site shows the lumaray as v2.
Does anyone have any feedback as to whether the mount has been improved?
