Strengths:    Very very bright, excellent car-annoying flash modes, long battery life.

Weaknesses:    Flimsy seatpost bracket, screwdriver required to change batteries.

Bottom Line:   
It's very attention-getting and the AAA batteries last forever. But if you're a mountain biker, look elsewhere 'cuz the bracket isn't beefy. I broke and lost the first one, got another on sale, and put it on the road bike. Cheezy bracket, but still blazin' bright!

Strengths:    Big, Bright, Multi-modes.

Weaknesses:    I don't know much about the mounting system as I made my own to attach it to my rear rack. But, after owning the light for a while, it blows through batteries and it constantly shuts off while I'm riding at any slight bump or vibration. This is very dangerous. It got to the point where I could only ride at night if someone were riding with me to tell me when it shut off (about 3-4 times in an average 6-10mile trip.)

Bottom Line:   
It was a good light, served me well for a couple years, but it is just farting out at what I feel is a premature time (had it for about 3 years.) It should have lasted way, way longer. Good design though otherwise.

Strengths:    it's big & BRIGHT

Weaknesses:    seatpost mount clamp

Bottom Line:   
don't even try to mount this thing on the seatpost. it will go away since the seatpost mount is just a piece of crap.

but if you prefer to put the rear light on your backpack, the strange design of this light is rather a feature than a bug. the belt clip is mounted to the light with two screws, so if your backpack has that little strip for rear light, it is possible to screw up the light just on the backpack, and it will not fly away for sure.

i ride with it for a year, and my mates call it "burn-eyes-out" :)

Strengths:    Great light, feels very safe and bright

Weaknesses:    Sorry to say, do not buy this. changing the batteries is a major pain including screwdrivers and at least 20 minutes of your time. if your batteries die on the road, you are screwed.

Bottom Line:   
Sorry to say, do not buy this. changing the batteries is a major pain

Strengths:    Bright, different flash modes, long battery life, works in the rain

Weaknesses:    bike mount is flimsy, annoying to change batteries

Bottom Line:   
I use this light for commuting, its got a clip on it that lets me clip the light onto the loop on the bottom of my timbuk2 bag. i've had no problems with it falling off and it always stays on my bag.

it can be annoying changing the batteries on it but overall i love it.

Date Reviewed: February 24, 2008

Strengths:    nice and visible

Weaknesses:    Poorly designed. Flimsy mount. Hard to install. Not easy to remove. Five screws must be removed to change the batteries...!?!

Bottom Line:   
This is a an example of poor industrial design. It looks cool in the package and uses the LED technology, which has taken years to evolve, yet the designers clearly didn't test the practicality of how easy the light is to install, remove, or change batteries.

Date Reviewed: December 28, 2007

Strengths:    brightness, pattern, lense size and shape - excellent visibility

Weaknesses:    quality control, durability. out of 6 or 7 of these: 2 were DOA out of the box. one is working, but has one dead led. lost one off my road bike when skinny part of mount broke from road vibration. one quit after riding thru a rainstorm. lost another one that fell off after the clamp bolt vibrated out. the current one is going to get tossed because it shuts off from cumulative vibration or big bumps.
batteries are a pain to change on the road/trail because you have to use a screwdriver to disassemble the unit completely to change them.


Bottom Line:   
avoid these like the plague.

Strengths:    - It is as bright as an aircraft carrier's landing lights


Weaknesses:    - Attracts UFOs if pointed towards night sky.

Bottom Line:   
If you're tired of constantly getting runover, but don't care about the alien encounters, then by this light. Who knows, maybe you'll make some new friends!

Submitted by Stefan Fuchs a Weekend Warrior from Linden, NJ, USA

Date Reviewed: August 22, 2007

Strengths:    Great visibility, thin, flat and airy design, sophisticated combination of 2 side LED diods.

Weaknesses:    After you mount it, don't even think to get closer to it. Very frustrating experience. Clamp is designed rather poorly, it's too thin exactly at the most important section. It breaks so easily. It you accidentally touch it with a little force, forget it, comes off the mount immediately as the reviewer before me, had the same kind of experience. That's right: It's great if you never need to move it or yourself around it. Expect to break it.

Bottom Line:   
What's the use of this great design, if if falls short on the mount? Cannot comprehend, why would they make the mount so flimsy when everything else seems so well done. Disappointing.

Submitted by Stephen Howe a Weekend Warrior from Frederick, MD, USA

Date Reviewed: May 6, 2007

Strengths:    Big and bright, good looking.

Weaknesses:    Incredibly flimsy mount. Clamp is incredibly thin and weak at critical points. Doesn't look like it, but after you break it, you see that screw heads are hidden in the mount, making for some extremely think plastic. Doesn't break in normal use, but if you try and muscle it around (like I did when trying to lower seat for son), breaks immediately, and you are left wondering at the near paper thin plastic where it breaks.

Bottom Line:   
It's great if you never need to move it. Expect to break its mount irrepairably if you try and change its position quickly. Won't be getting another. I have a hard time understanding how the mount could be so flimsy when everything else seems so well done. Frustrating.

Submitted by Dwight Kellams from Fishers, IN

Date Reviewed: October 9, 2006

Strengths:    Use it for road cycling only. Highly visible which is what you buy it for. Strong seat post clamp and light screws into clamp and is held securely so there is no danger of vibrating loose.

Weaknesses:    None unless you consider that a screwdriver is needed to install batteries. Some complain about this on the 3.0 model but I like the fact that it is a rock solid design.

Bottom Line:   
Very solid product and only $10 so it was less expensive than other brands. I purchased a second one to attach to the rear of my jersey for even more visibility. I have not used it this way yet but the clip is substantial and appears to be up to the job.
