I have a couple of the previous ones. The zoom bit can rattle a little, also the batteries inside pick up the road buzz but you can sheathe them with tape, paper, rubber band, etc and cut that out. The diffuser part is new. I've found that with one on a wide focus and the other on a narrower one you can get pretty good lighting for poorly lit roads - not dead of winter rural nights, though. 7day shop sell handlebar mounts for about £3. I've dropped them in the road in the past and gone back and found them completely undamaged and I once hit an oncoming car full on, went over the bonnet, the light hit the front of the bonnet as the bike tipped me off. Again undamaged. Apart from a rather nasty dent in the car bonnet, that is. Worth a punt, I'd say. Some people have used slightly longer casings with a more powerful battery but I just use 3xAAA rechargeables without issues.
Had a Cree type one but didnt like having a battery n cables attached to the bike
