Rated 1 out of 5 by cziasai Steer well clear.
Bought back at the end of August so my partner could ride the 500m to her stables. Two thirds of this is on-road. She used these light under ten times to ride the 5 minute trip before the battery went. Since November it proved easier/safer to drive thus the bike sat in our garage on the side of the house (not damp). She now wants to ride again but the Front light stays on permanently, unless you remove the battery! The button control does nothing. Total rubbish - knew I should followed the reviews. Seeing as she didn't need huge lights I thought these would do. Steer well clear. Rear light works intermittently.
Doubt I'll get a refund or replacement.

Compact, quite bright and easy to fit - should get you home in an emergency. Cover gets dirty very easily

Rated 3 out of 5 by Anonymous Old ones have problems
This is a bright light and gets you noticed. Build quality is fair - seems to be an issue with the switches as my second one, which was a warranty replacement (CRC handled well) is now playing up. Sometimes switches off (or rather, will not stay on after being switched) and occasionally won't switch off. Both mine were July 2010 models (sticker just visible inside) and i think this was a duff batch. If this issue is fixed then i'd have a new one, or may go for the Cateye Reflex (have a rear Reflex and it's awesome).

Rated 3 out of 5 by Anonymous This is a superb bright light but the only thing that i found annoying was that sometimes the light would change from steady light to flashing when i hit a bump in the road, i have tried a couple of these and they both did it flippin annoying apart from that a good light.

Rated 1 out of 5 by Anonymous 2nd unit just failed
I've been through two of these in one year, on a flat commute on urban tarmac roads.
When they worked they were very bright, and the mounting system works well too. However they both broke in the same way, and after roughly the same amount of time (2 months); the switch became stuck on a strobe setting, and the light became very faint. Replacing the batteries doesn't fix this.
Some other people here seem to have had really good experiences with them, so I guess its a bit of a lottery.

Rated 4 out of 5 by Anonymous almost perfect
Boomers are extremely bright and they get a ton of attention, which is the reason I got these. I wanted to be seen. I bike in moderate traffic and these ensure no one will miss me, unlike my previous planet bike lights that did little to point out my presence. The boomer design is ingenious (to a point). They require no additional mounting hardware or tools to install or remove from the bike. Quick and easy. Not to mention they look fantastic turned off, too. I got the clear bodied units front and back and they almost disappear into the frame. I'm a minimalist at heart, so these are just about perfect. The only real drawback is the light bleed from the front LED which can be distracting on pulse on a very dark road. Switch to constant, aim the light down and the issues is better resolved.
Overall I'm pleased with these little lights. No unsightly plastic hardware, easy on/off the frame when I park and super bright with attention getting strobe patterns.

Rated 5 out of 5 by Anonymous Blinding!
Bright enough to have epileptics on the road ahead of you convulsing by the time you reach them! I love it and have it on blink on all but the brightest day just so those ahead can see me coming, a big help in Ireland with so many s*** drivers on the roads. No weather issues as reported elsewhere.

Rated 4 out of 5 by Anonymous Does a job for the dosh
I use this as a "be seen" light in flashing mode alongside my 900 lumen "to-see-potholes-in-the-dark" light. Also if I'm heading out for some late in the day miles I just strap it to whichever bike I'm using in case its getting dark or dull by the time I get home.
Good points: Bright, easy to fix to the bike (never had any problems like another reviewer), small, you will definitely be seen. I washed this light at 40 degrees, including spin cycle (accidentally). Opened the washer and there is was, flashing away. Hence it is weatherproof, despite the comments of another reviewer. But, you need to make sure you get the silicon shell back on properly after changing batteries, otherwise there may be leaks through holes! The build quality is fine - another reviewer said the actual guts of the light is poor quality - this is what they all look like, the only diffrence with this light is you can actually see it when you change the batteries.
Bad points: I've read elsewhere that folks have had problems with this light being switched on in their bags, and indeed the on-off is sensistive (you can turn it on by putting down too hard on the table).
This is a good, flexible light. It won't do everything for everybody, but I am yet to find the light that does. It's 22 squid, and alot of dosh that ain't. If you want a small, easy to use, cool looking, bright light, then this could be for you. If you want a better, brighter, stronger etc. jobbie, then you probably need to be in different market from the 20-25 quid range.
