Light is good. Mount is subpar. A metal disc on the light attaches to the rubber strap and eventually tears it -- broke after not much use, rendering the light kind of useless.

I've had lots of lights. . . this is about as reliable, compact and easy to use as they come. It's also my first USB light, I'll never go back. Ended up buying one for the lady friend.

Very bright. Easy to install and remove. Battery lasts forever.

Love this light. Compact, light, bright and rather stable. Quick to put on and fits any bar snuggly without scuffing your carbon.

Exceeded expectations Excellent light intensity Exceeded expectations Excellent light intensity Very good useful battery time Very good quality materials and a very light Highly Recommended

I bought 3 of and have them all attached to my helmet. Light, versatile, very functional and well made. I do a very wide variety of riding and they are equally useful on the street, on the trail or on the fire road. 1 is def bright enough but with 3 of them I never have any issues with darkness. They charge pretty quickly and hold a charge surprisingly long. Super glad I found this model and I highly recommend it. 24/7Rider

Insanely bright for its size, it replaced a 100 lumen Bontrager Ion 100 R light that was swiped off my handlebars. Long lasting battery, which was expected given its triple the size of my last light. The body has a nice solid feel to it without feeling too hefty. Side visibility is much better than my previous light and the battery indicator is nice and gives a more advanced warning that my last light. The gripes? The control(s) are clunky as the modes are cumbersome to cycle through and the button has a thick rubber cover making it a bit hard to press with gloved hands; a small price to pay for good moisture resistance. I would have preferred a mount that stays on the bike, rather then wrestling with the strap after every trip and having to re-aim the light. Also, the thick strap offers a lot of compression force, and given my tapered handlebars, the light constantly 34;walks34; and aims to the left; the strap also makes on the fly adjustments a little difficult when alternating between shining into traffic and illuminating the pothole ridden terrain being consumed by your front tire. I tried to tough it out and grow accustomed to this light, but the little plastic retaining tab holding the rubber strap to the body cracked. Had to return this one; I may consider buying one of the upgraded models as a replacement.

Perfect for a road bike where it's small size is crucial. Highest lumen setting and blinking feature are really the only usable options though. Light weight.

Great light for the price ! small,compact,powerful and not expensive

You know you have a serious light when you can see it reflect off Stop signs from half a block away! Love the way it's easy to re-charge.

I have far more powerful bike lights, but this is my favorite. It is simple, small, well built, and powerful for its size. It charges fast if you have a 1 amp phone charger, and the charge lasts longer than claimed. I am not sure about other peoples experiences with this light, but mine has been dead reliable and trouble free. Be aware that this light is more of a flood type beam, meaning its beam is wider and covers more area near you, which sacrifices some distance its beam travels, but it is sufficient for most riding just by itself, and works well with other lights also.

As with others, I also had mine die after just a couple of charges. It still charges okay, but it can't hold it: after just a couple of hours of sitting on a shelf it will lose all of its charge.

Small, light but powerful. I use it primarily for daytime rides, utilizing the flash mode. It is very effective, even in full sun. The battery charge life in the flash mode is quite good. Other reviews mentioned the mounting band not holding very well. I have had very minimal slippage, it hasn't been a factor for me. I would purchase one again.

Great little light at a good price. Four stars because it is not removable from the mounting strap like the larger versions and recharging port is a little difficult to plug into.

I've been using this for about 5 months now. Here's what you need to know: - It's very well built. - It's pretty small, fits in your pocket. - It is rain resistant. I rode it through heavy rain dozens of times without any issues. - It's more than powerful enough for commuting/riding in a city. The beam is pretty good. I would want something stronger for night mountain biking. - It attaches with a rubber strap. It's very easy to mount/unmount and it stays in place pretty well. There is no separate mount that stays on the bike. - It charges via USB only. - I won't describe how to switch between modes here, but what you need to know is that it basically has 6 modes: low, medium, high, blinking, super low, and 34;locked34; (so you can't turn it on accidentally). Accessing the low/medium/high modes is dead simple. Accessing blinking or super low mode is annoying. Locking/unlocking the light (which is optional but handy if you put the light in a backpack) is very annoying. So why only 4 stars? Well I bought one, took it home, and it was dead out of the box - I think it didn't charge. I brought it back to the store and they replaced it with another that worked. I found that several other people on the internet had the same issue, or that it couldn't be recharged after some time. So I'd suggest you buy it from a seller that has a good return policy.

Run time lasts as advertised and charges much faster with phone charger instead of usb to pc. Perfect light output for handlebars. Works great when paired with a lumina 750 mounted on the helmet for mountain rides in the dark.

I use a Lumina 750 with excellent results. Picked this up for the wife as she doesnt quite require the power of the 750. Its a great little light. For the money, It would be hard to beat. Plenty bright for the average person to use for street riding and trails. Lightweight is a bonus.

JUNK ! Charged ONCE then won't charge.. This is the 2nd one that I have had probems with.. Purchased the 550. It lasted several months until stopped charging.. Liked the light (when working) so got the 350 .. Still seemed very good light (working). BUT when tried to charge for the first time it would not charge.. Their USB charging system is faulty.. Save yourself the grief that I have experience and save your money.

Quality compact design. Allows you to quickly attach/detach without having to use a mount that stays on your bike.

Initial impressions as I have only owned it for a few days. Quality seems spot on. This thing is BRIGHT and can be seen from a fairly wide angle,not just head on. Rechargeable battery is nice and keeps the overall size compact. Quit messing around with cheap bike lights as I mistakenly did and buy this first.
