2. The handle bar attachment does not inspire confidence to me, especially if it gets exposed to the elements a bit longer. Having such an expensive light on the handlebars means that I will need to remove it each time I lock the bike outside (which is nearly everyday), so the constant mounting and removal will inevitably cause the mount to break. Of course it has not broken yet, but it's the engineer in me thinking ahead.
Odd, I have the 350 version for over a year and half and haven't had any problems, in fact I really like the handlebar attachment, it's been very sturdy compared to some stuff I've seen. The little rubber thing on mine hasn't come off, but I've seen a lot of lights with similar cheaply built rubber crap even on much more expensive lights, you just learn to be careful, they don't want you to own stuff forever...sad but true. But the good news is that since you just bought it it still has a 1 year warranty, send it back for replacement or maybe they have a aftermarket thing they've come up with they'll send you.
