Don't do Facebook. Using forums to gauge reliability is only useful to see what problems occur, not the relative numbers affected. People without issues tend to be less motivated to post - or to even read forums (and hence, your post) in the first place. Your poll will be inherently biased towards those reporting failures.If anyone fancies helping out I have a poll going on the photon owners group to help establish reliability for people sitting on the fence to purchase, myself included...

My Photon motor has had no major issues after a year of off-road and back country use, 1250km. Mine was from one of the earliest batches before they started to have scaling problems with long wait times.
Left bearing is feeling slightly loose and slightly rough (with the plastic shield/bushing removed) I expect to have to replace it in the next few months. Still in much better condition than the previous Sram DUB BB left bearing, which was complete rubbish at <500km.
Left crank used to continually work loose, have replaced with some others, yet to see if the issue is resolved. Several others have had the same issue.
