Hello all. After reading all the glowing praise here, I bought a superflash last week. I ended up mounting it on the left seatstay, probably not the best place but my old Baycliff saddlebag is in the way, and the saddlebag has no blinky mount. Anyhow, it was fine for a few days, but today I hit a decent bump, nothing bad, but the superflash ended up flying out of it's mount and shattering on the pavement. After buying a new one this afternoon, I attached a zip tie to the release tab to make a more secure attachment that you can see in the picture. You don't even have to bend the tab much more to release the superflash, but it fits in there snug now. I haven't road-tested it yet, but judging from tugging at it and such the light isn't going to be flying out too easily.
I searched the forums earlier and didn't find any posts similar to this, so I thought some of the many superflash owners might like to try this.
