Work well

The mounts work well, magnet is strong enough to hold them firmly in place even over rough terrain. My one complaint is that it can be difficult to remove the light from the mount because the ends of the straps interfere with where you want to put your fingers to pull the light out of the mount.

Quality construction but ...

But there's not much info on how to actually use the press to release clips on one's bicycle. Came to the website looking for answers. Not finding pictures of what those clips are for and how to use them! More/better documentation in general would be helpful!

Great lights, but don't mount easily on thin rack stays

I love the lights and have them on my handlebars and on my trailer, but the attachments don't really work well on my rear rack stays. The mount is not quite "universal" :-)

Can hold firefly securely.

The mount can hold the firefly securely.
