I just bought two of these, one headlight for my bike and one for my husband's. They are so easy to install, you just pull the streachy strap aroud any bar you want to place it on your bike and hook it around a hook on the bottom of the light. We thought these would be good ones to help make us visable to motorists while riding at night. we didn't realize that they were so bright! We tested them on a dark street and could actually see where we were going! I have a big basket on my bike so I attached it to the front bar coming from the tire to the handlebars underneath the basket and it works great. I was so worried about finding a light that I could use with my basket. The nice thing is too, is that my bike and the blue Beetle are the same color and you can't even tell that the light is there unless it is on. All in all a great buy!

For the price you are paying, it is definitely worth it, it's slightly small but it shines. Very handy little thing to have for a bike ride at night.

I hope that should anyone purchase this bike light that they realize on tiny it is. To put into perspective it's about as small as a baby's fist. Therefore this can pose a problem when you want to strap it onto your bike since it might be too small and not fit around the entire diameter of your handle. The way the light works is that it's shaped like a tadpole, the tale end of the light wraps around the handle and there's a hook at the head where the tail comes around and attaches to (which you can somewhat see in the picture). The material the Knog is made of is flexible and somewhat stretchy.

The light itself is a little bit sub-par from what I was expecting based on the reviews I read. Yes, it can be quite bright for such a small light, however it's only effective at close distances, and if you ride your bike like i do, you'd rather know of cracks, bumps, etc six feet in front of you instead of maybe 2-3 feet. At farther distances from it's optimum 3 feet, the light becomes significantly more dispersed and less concentrated.

There is also the smaller issue of turning the light on and off. The Knog functions by having you push down on its head to push a button underneath its skin, and in order to turn it off you must click through its various modes. I find the other modes a tad bit excessive and would rather have a light that turns on and off or at least provide the option of going to certain modes directly.

I bought this about six months ago, and just keep it on my road bike at all times. It's sleek-looking and adds basically no weight. When I really plan to ride at night and go somewhere, I use a heavier-duty light, but this is good to always have there -- I often turn it on flashing mode even for day riding.

It's not enough to really light your path, but it is fairly visible for its size. Fun and easy to take on or off. The only real issues (pretty much all easily dealt with):

1. The batteries it uses are obscure, and very expensive if you buy at brick and mortar stores. But you can buy generics quite cheaply online. Still, not as convenient as standard AAA batteries.

2. There is no obvious indication that your batteries are dying. The lights just get dimmer and dimmer, and eventually you realize something's wrong. Still, mine lasted a very long time, even forgetting to turn it off at times!

3. The silicone casing does attract a bit more dirt than regular hard plastic. But it can be removed from the light module fairly easily for a thorough cleaning.

4. If mounted with the light on top, the light shines annoyingly in my eyes. This was easily fixed by just mounting it upside-down -- just make sure it's angled up enough so it's still clearly visible to traffic.

I also disagree with others' statements that you need to remove it to prevent the silicone from stretching: I've left it on almost constantly for half a year, and it fits just as tightly as ever. Overall would recommend this. It's especially great for bikes (racing or road) where you wouldn't want to screw on a heavy headlight/mount.

*****Updated 02/05/2013
Beware of cheap Chinese knockoffs. I recently purchased two Waterproof Double White LED Light with Black Silicone for Bicycle. Also posted a review and photos on that item. The knockoffs are not water resistant and will overheat fairly quickly.
***** End Update

These lights are perfect for their intended use. Bicycle lights should either, make you more visible to others or help you see the road in front of you. These lights make you more visible.

I've been using three everyday for about a month, two red and one white.

There have been complaints about receiving defective lights, some of these may be due to people not removing the plastic disc that separates the batteries from one another.

As for people complaining about too many settings... engage the memory function on the light.

1.Turn light on
2.Click through to your desired setting
3.Depress (HOLD) the button until it turn off
4.Click power button once...
5.Your light should automatically default to your previous setting.
6.EVERY time you turn light off, Depress (HOLD) the button until it turns off.
