...and best of all it does *not* use a built-in rechargeable battery. You can put rechargeable batteries in it if you like, carry a spare or pull into any convenience store at night and buy a new one. It's really well built, too. Very happy with this.

Recently started biking after 2 yrs break.This is a 2nd light i bought, for my wife.1st one works well and bought maybe 5 yrs ago. The battery is good and after my 2 yrs break it still light up. Bought a rechargeable one and have to charge after 2 rides.My main rear light to go. Very bright, unique light pattern and long battery.Highly recommended!

I've been riding with this light nearly daily since 2012, with a pair of Eneloop AAAs inside.The batteries last for many weeks (at 5+ hours of usage per week), longer than I've bothered to track. I just recharge them roughly monthly, but I've never had them run out or have the light get really dim.The light is bright, and I like its various blinky modes — I feel like they increase provide a better riding time/visibility tradeoff than "steady" or "regular blinking".I also appreciate the tactile design of the button — I find it easy to turn it on/off by touch when it's on the back of my helmet.The physical design is nice too: the light is lightweight, the o-ring + mount design has kept water out of the light in all my rain riding, and the diffuser provides a little bit of side visibility.I also love the customer service. About 4 years into my ownership, one of the wings on the black mounting bracket broke off while changing batteries. I was able to "fix" it with duct-tape, but I also e-mailed customer service — they were helpful, polite, and a week later, I had a new bracket in the mail.I highly recommend this light, the price-performance is the best I've seen among the dozens of lights I've owned. Consider using quality NiMH batteries if you ride a lot — it's easier on the environment, and saves you shopping for batteries.

La mejor luz trasera de bicicleta que he comprado jamás.En la bici, que nos vean bien los automóviles y otros vehículos a motor es primordial para nuestra seguridad, y esta luz llama mucho la atención, por lo que el conductor debería estar ciego para no ser vistos.Este piloto es sencillamente ¡Impresionante!Tiene una potencia de destello muy buena y desde que la llevo, los coches y pasan mas retirados al adelantar, eso da mucha seguridad cuando uno va en bicicleta. La llevo siempre cuando salgo por algún camino o carretera que pasen vehículos, incluso de día.Por el precio que tiene no es para pensarselo, ¿cuanto vale tu vida?.

It really is a great product. It is very visible, the mounting and the supports look like they will hold. Easy to attach / detach if needed.

This light is stunningly bright. I wear it clipped to the back of my helmet. It clips on to the helmet adjuster perfectly.The light is blinding - so watch out for complaints from car drivers who get caught behind you and are being blinded.It really is that bright!!

I do a lot of cycling - about 5000 miles a year. A lot of that is at night because I do a lot of very long rides that take more than 12 hours to complete. I may be a little paranoid, but I really don't want to get hit by a car so my tail light is a critical piece of equipment. Whenever I see a cyclist with a really great tail light I ask them who made it and where they got it. Last November I saw my first cyclist with this tail light and I was so impressed I had to get one. Up until now my best tail light has been an eclipse which I still use as a backup. I would rather have a Dinotte but they're way too expensive for me.So what's good about this light? Well it's very bright and has two 0.5 Watt LEDs which is the same total brightness as some headlights and this is better than one 1 Watt LED because you can have more flash patterns which is very important. I have a theory that motorists pay more attention to a group of cyclists than to a single cyclist. At night, a motorist that sees complex flash patterns assumes that they are approaching a group. This light has complex flash patterns all on it's own - therefore I think it's a safer tail light. It's also easily visible at half a mile which gives motorists time to zone in and drive approriately.The light takes 2 AAA batteries (I prefer AA but you can't have everything). Even with AAA batteries the run time is an acceptable 50 hours (depending on the flash pattern you chose). The light is a bit chunky but fortunately there are a number of mounting options including seat post, seat stays, and saddle bag. You should have no problems mounting even if you ride a small frame.Turning the light on and off and selecting flash pattern is fairly easy with a pressure switch on the top of the light. I've had some feedback from cyclists behind me in the pack - they hate the flashing because it's so bright - no problem I say, just come around me and pull for a while :-)Twelve Month update: This light has developed some bizarre issues...1. When I set it to solid mode it will flip to flashing mode a few minutes later for no apparent reason. Not cool when there is someone trying to draft you.2. Turns on too easily. Many times I've put it away and I come back next week and the damn thing is weakly flashing. I know it was off when I stashed it.3. Yesterday it would not turn off. Whenever I hit the switch it just toggled from fast flash to slow flash mode and back again. Had to remove the batteries, then leave it for 10 minutes, then put the batteries back in.All these issues indicate a faulty switch. I might try contacting the manufacturer.
