5.0 out of 5 stars Bright, multiple settings, May 17, 2011
Amazon Verified Purchase( What's this?)
Like its matching front headlight, the rear knog boomer is plenty bright. VERY visible, even at high noon in broad summer daylight (now that's saying something!). There are multiple flash settings, which is nice. Couldn't really figure out how to fit it on my bicycle, so I've been keeping it attached to the seat post- could be a problem if you have a rear bike bag attached there (I use a messenger bag). Only takes a few hours to charge up bright, flashes once during shut down when the battery is low to let you know. Love the USB rechargeable- worked for 10 hours straight out of the box (on constant light, since its been dark and rainy the past week or so). Good little light, makes me feel safe riding even on a rainy evening. As always, completely water proof. Sensitive enough to turn on and off even through gloves, but again, wouldn't recommend throwing it in your bag with other things since it might flick on. No problems with maintaining its mode, even on rough patches, if inserted... Read more

2.0 out of 5 stars WANTED TO LIKE IT, May 14, 2012
By 
TJ (Midwest) - See all my reviews
Bought one of these from Amazon after liking my front light. Have not had any problems with the front. However, I've gone through 2 of the rear lights... After awhile it would not turn on after a full charge, it will just flash once and not stay flashing when I press the power button. Bummer. The replacement worked for awhile too until it had the same malfunction, making it unusable. Knog's customer service was not helpful and said to return it again.

Overall: GREAT CONCEPT in lights, love the USB, love the silicone body.
What I dont' like: Hard to turn off, there is like 4 modes and when I get to my destination, the last thing I want to do is cycle through all the modes until it gets to the off position, which takes like 10 seconds to get there. Anoying. I also dont' like that they seem to have a faulty circuit on two of the rear lights I bought!

4.0 out of 5 stars Too many modes, otherwise good., December 20, 2011
Pros
- Good physical design. Fits seat post well, and looks good.
- Bright, for a safety light.

Cons
- Too many modes.
- Button is hard to find with gloves on.

Make it have only flashing, steady, and off modes. Make the button easier to find with gloves. Don't try to remember my last mode, since I want different modes at different times.
