Have now this bike light for the second time (first was unfortunately lost) - it is robust in rough everyday city, has a very bright glare-free light on the road and sufficient width to dark cycle paths and underpasses. That you can with 4 AA batteries to operate (I extern charging) makes things cheap and easy to handle. By the way, did not lose the first because the holder was broken - the snap closure keeps very reliable and has barely worn in 20 months a lot of use. On bumpy roads with stakten blows I would still secure with NEM cable ties.
I would recommend this product to buy even a third time :)
