Chisela Accessory Mount

I've been using two accessory mounts with an action cam and a Bontrager Ion Pro RT. Actually, these mounts are the main reason why I bought the Chisela 'cause I saw in it a great potential as a snap-on accessory mount. Since the Chisela is tilted upward, gravity holds the mount in place...to a point, of course. It worked reasonably well, and so far I'm happy with it. Given the weight and heftiness of the devices, I think the mount performed admirably. Only had one instance of the light getting ejected when I rode over a pothole at about 25mph. (The light survived, thankfully.) As the tying-down screw would defeat the purpose of it being a quick-change mount, I'd have to come up with another way to hold it down.
