Review on NiteRider Lumina Micro 650: USB Rechargeable Bike Light for Enhanced Safety & Visibility in Road Cycling Adventures by Cesar Carter

Very small but very bright, I particularly like the strobe function. The light itself gets 5 stars considering the size and performance, quite good. Now the problem, oh my god. The mount is a clamshell with very fine stainless steel threads and when fitted to a 1" handlebar extension it has to be unscrewed about 1/3 of the way to open and then 1/3 of the way back to install, my threads went bad right away and didn't move Put some 3 in 1 oil on it and after about 10 minutes it loosened up but still had to unscrew/unscrew the fine threads with a tiny cog and then barely holds the light in place with the spacers provided, constant adjustment throughout required for the journey. And the load release slide quick release is loose and the light jumps in its mount. I have since made personal modifications to make it work but I didn't have to, the very cheap mount made for a great poor quality product.
