Getting a bit repetitious but:
‘Older’ AyUps for three winters, used fairly frequently for MTB and daily for commuting. I prefer the helmet mounting over the Joystick as I can mount the laps well forward (just above the visor), the batteries on the back and the overall height of the helmet is the same. I run the cable between inside the helmet, and hence no snagging risk.
I’m about to get the light units upgraded with XPG emitters and revised optics; you can get this done by AyUp but requires return to Oz (they reckon 10day turnaround).
I do find they don’t produce the overall levels of light that say Trouties offerings do, however I don’t have ‘shadowing’ problems from mates lights as I’m always too far off the back of the group…
Overall, v. happy.
