Perfect brightness for what I wanted
I got two of these for my kids because of the auto on/off feature - AND - because they are not that bright. (During the winter months -before the time change and around the winter solstice- it is still kind of dark when they leave the house for school.) I didn't want a "super" bright light, or really even a "bright" light, because kindergartners and younger kids are eye level with it and I'm not eager to find out which kids haven't been diagnosed with epilepsy yet. -Essentially, this light is bright enough for cars on side streets to see at crossings without being bright enough to hurt a child's eyes whose standing directly behind it (in our suburb, kids are supposed to ride on the sidewalks - this light is to help cars see my kids at crossings). ....It's exactly what I needed.

Great light!
Nice product, works as a standard, fairly bright rear light - steady or flashing - when not braking. When coming to a stop, the light gets brighter, giving me an extra degree of safety if I ever need to apply the brakes suddenly at night. There's a threshold of acceleration for activating the extra brightness, so it won't come on if I slow down very gradually, which isn't needed anyway. The light attaches easily and securely to my bike and is also simple to remove for everyday use.

IT STOPPED WORKING AFTER 4 MONTHS
I expect no less from China. My bike is in the garage, not outside. I bought 2, one for me and one for my Wife and guess what? GUESS WHAT? THEY BOTH STOPPED WORKING AT THE SAME TIME!!! Not one.. BOTH!!!CHEAP JUNK! DON'T WASTE YOUR PRECIOUS DOLLARS.

Works as designed
Works as advertised, however I didn’t realize that it requires AAA batteries and not rechargable. This may keep it more waterproof. I’d like a little more if it were just a little brighter though.

Piece of Crap
The rubber supplied with the product was either too big or too small to fit my Specialized bicycle. When i used one piece of the rubber, it fell off when I was riding. When I tried to use both pieces, it wouldn't fit. In addition, the light is so dim, you can't even see it in the daytime and barely at night.Don't buy it.!

Works like a charm
This is perfect, works as if you had a car... really lights up when reducing speed and absolutely no worries - don't even have to remember to turn it on! - ideal for a teenager. I wish they had a front light just like this one.

Doesn’t turn on/off so easily
It doesn’t easily turn on/off so I had to take it off the bike to try and turn it on. It slipped out of my hands and fell on the ground. The on/off button popped off and I had to superglue the on/off button back on. This happened the first time I used it.

Motion Sensing Technology Performs Well
I like this light on my bike, but I don't like having to hold down the rubber button 3 to 4 seconds for powering it on and off.
