got mine today and made a full video review, with comparison to the pbsf.
i've used knogs as supplemental lights for a long time, and i think the quality of this light is way better than their other lights.
the end of the review has a comparison to the superflash.
here it is off-axis view in 4pm summer bright sunny daylight conditions under the shadow of the I-5 (read: HUGE) bridge...
it definitely won't wear out quickly, even if you're taking on and off the bike several times a day. the clip it uses is a very durable medium density hard plastic and the shape of the closure makes it stay on easily and come off without damaging anything. they use the type of silicon you'd find in sex toys, and it lasts and lasts unless you take a blade to it or were to literally pull it apart and try specifically to break it. with normal use it will last longer than a PBSF, and i'd put money on that bet.
this thing is AWESOME. I'm very, very happy with it.
