Mounted this to the bottom of my handlebars on the drops.
Has a nice swivel built in to adjust direction of beam.
Perfect.
Pros bright, sleek, nice flash options, sturdy, good battery life
Cons rubber band base does not have much slack. It works on my round drop bars (only barely) but may prove impossible on aero bars.
This is a great light with a long battery life. The light has multiple modes of brightness and strobing options. I honestly forget to charge it because it lasts so long between charges. That said it's a little heavy but that is more from the larger battery and I assume metal frame. Still, I highly recommend this light. Quickly switches between bikes with an adjustable strap.
I have another Lezyne light that I like but wanted something a little brighter but also that the battery would last longer. It's certainly brighter with the two beams, but even in low power it doesn't seem to last any longer than my smaller one, despite the fairly large increase in weight and size.
I'm also not a fan of the hard molded bottom as the shape doesn't fit my handlebars very well, so it's somewhat difficult to strap the light on.
The light quality is good. Very bright. Works well. However, the mounting strap is too short. It will barely fit on a standard 31.8 mm handlebar. You have to work at it to get it to fit. I almost sent it back because of that.
