Great rear light, very, very bright.
Poppycock
The first one I had, the on/off button stopped working after the first day--it got stuck while on and I could never turn it off again.

You can also get a wall adapter (with a USB plug) so you can recharge it without a computer.

When it works, the white Blinder is bright enough so that people on the sidewalk complain if I haven't turned it off the minute I walk my bike onto the sidewalk to lock it up. I can also light up street signs two blocks away. However, the design or quality could be improved. The first one I had, the on/off button stopped working after the first day--it got stuck while on and I could never turn it off again. Because of the warranty, the merchant replaced it for me. The second one worked great until one day when I had it charging in my laptop and then I unplugged my power adapter on my laptop while my laptop was still on. There were no warnings saying that you couldn't leave the Blinder plugged in but your laptop not plugged in, but then the Blinder stopped being able to charge. Once it drained it was dead for good. The merchant replaced the Blinder again and now it's been several months and it's still working, but at this point I don't have great confidence that the light will not fail again.

I have a red Blinder for the rear light, and it hasn't had any problems.

The bottom line is that I like the lights enough to keep them (and to ask for them to be replaced when they fail), but I am hesitant to recommend them to others because I've had to replace the front light twice.

2014 Update: One side of the strap broke on both my front and rear lights after nearly two years of use, but they were replaced under warranty. On my rear light, one LED also burned out within two years.

the blinder was easy to charge using the USB and clipped nicely onto cannondale handlebars. Very bright and a nice wide beam for trails giving side to side visibility. Have a regular "flashlight" style on other bike and would choose Knog over that one next time!

Great light. Love the way it recharges directly into your computer. Very visible by cars and others. Perfect for handlebars, easy on & off.

A powerful light, good for riding, running in the dark. I use this light for running, I attach it to a running belt. You could put an extra rubberband over it to secure it on a running belt with minimal bouncing around or movement. I chose this for running because I do not like to wear headlamps. This still provides enough light to run in areas with minimal to no street lights and it definitely makes you visible! You will definitely be seen with thing on no matter what type of sport you use it for.

USB charger worked great. It charged within a matter of a couple of hours. It stays bright for several hours, and easy to use. I would definitely recommend this other runners, bikers, whomever can attach it to something while exercising in the dark.

One star for design. One star for brightness. A great idea being able to charge this through a USB port, however, the company claims that it can last 50 hours on the blinking setting. Not true. At full charge, I've found that it only lasts about 3-4 hours. That's quite a bit less than 50 hours. Also, I had some technical questions about mounting this light, so I went to Knog's website and emailed customer service explaining my situation. I never heard anything back from them.

False advertising combined with poor customer service is not a good thing. If you want an overpriced, nicely designed, bright and compact light then go for it. But don't expect much from customer service, and don't expect a full charge to last long. You can get a better product for less money.

I was stoked to have this slim, portable, and bright as hell knog blinder headlight on my bike. It was bright and everything about it was perfect until...

In fact, these things happened with my knog rear light as well.
a. the light stopped working after my 3rd time using it (headlight only).
b. the strap broke loose in the middle of the ride (both lights).

The strap is made out of rubber and supposed to stretch very well but there is no way it fits an average sized handlebar. I was afraid to break the strap every time I try to put it on the bike.

Remember, once the rubber thing breaks, you are done.
total waste of money. I have been using Serfas for a while now and it is so much better.

This light is very bright and useful for being noticed by cars. It is easy to attach and easy to install and remove. Very lightweight and compact. I did not give an otherwise great light five stars for a few reasons......it does not charge well for me via a computer USB. It would die quickly and there are risks stated in the instructions that the light could be permanently damaged if the computer shuts down while the light is plugged into the USB. I switched to charging it directly in the wall socket via USB adapter, and this works well. I also found that the light only lasts a few hours on a heavy blinking mode, perhaps a little longer on a less frequent blinking mode. It lasts nowhere near as long as claimed. Also, it does not stretch easily around fatter bars and I have difficulty placing it on my road bike due to brake and gear cables. As a result it angles slightly upward which causes some distraction while riding. Regardless, if this light fits your bike well and you are satisfied with only a few hours run-time, then this is a great light. For me, I'm happy enough to keep using it.
