Yes. I have one. And it’s about to go back again… (3rd time).
The reflex keeps on packing up so it burns through the battery really fast. But you need the reflex settings as the standard settings are not really that bright. (I know that is relative, and compared to 5 years ago, it would be really bright….)
But it does work well when it is working. It’s fine for short solo rides when combined with a headtorch.
BUT if I was shopping now with an exposure-type budget, I would probably consider something else. I like the look of the Four4th Rameses. Self-contained, 5200 lumens and the ability to screw in another battery for really long rides. Anyone got one?
