Rated 4 out of 5 by Anonymous Good Rear Light
I've not had the problems others have voiced after a year of use with both the front and rear boomer. Mine are the USB model. Compact, bright, easy to install and use, it is my primary "travel" light when I take my bike on the road. The only design change I would make is for the USB cap to snap more securely on to the housing so that when you take the light out of the outer "boot" the cap comes with it and you don't have to dig it out of the bottom of the boot.

Rated 3 out of 5 by Anonymous not good
Battery discharges too quickly and without use. Did I get a defect or is it a common problem? 20£ or even 15£ (on sale) ain't worth it! I'd go with Knog Srobe instead.

Rated 3 out of 5 by Anonymous good looking but fragile
After two month of use the internal clip that keeps the batteries has broken up and know I have to disassemble the light before half of the rides and it can switch of after some bumps.
The light looks great and I really like it but internals are fragile and the clip needs some upgrade in future models.
Also it holds dust and dirt well thanks to it rubber body but it can be easily washed.
And yes, it's amazingly bright!
