I like that it's rechargeable, I like the good battery life, and I like that it's bright enough. One thing I don't like is that it can't be used on rainy days. If you're going to wash your bike, take it off before washing; water easily gets in and ruins it. So far, this is my third one; water is like Kryptonite to this LED bike light.

Sooo this $15 light is identical to another one that sells for $35, under another brand name. Shhhh! This back light can be subtle so you don't offend your other bike mates on dark paths, or it can blink like a rescue helicopter: your choice. Some people complained about the rubber-band mounting, as I was concerned, and I have grown to love it: it comes with several duplicates and different rubber bands, that are proper silicone quality. The design purpose is to stay on your bike, and not ever move, and not get in the way. You could put this on a mountain bike and go off jumps with confidence. It's elegance in simplicity and I have no problem removing it for charging. The charging port is protected by being mounted on the bike. If you complain about this, you failed to consider other factors. It's very attractive on a minimally equipped road bike. I've had it out for three hours on max blink and didn't come close to needing a recharge. This back light gives me confidence in traffic.

By versatile, I mean that I managed to easily mount them to a number of places on a couple of Rad City ebikes. The bikes came with a tail light, but they're geared for darkened conditions; virtually invisible in sunlight. These are not and at the same time, haven't managed to annoy me as I follow my wife's bike. We ride for enjoyment 20 to 30 miles several times a week - I've ridden behind bikes with major lumens and they can pierce your skull in the first five minutes.They're simple, not particularly waterproof, depending on the mount site, but pop on and off easily for recharging. I think doubling up on them for our bikes is in the near future.

Love the sealed design with integrated USB rechargeable battery. Case is watertight won't leak, won't fall apart on impact or with jarring, and the on/off switch appears fully rubber sealed and waterproof yet easy and accessible to use. Bright and visible when on and several blink/steady modes and brightness setting to choose from. Only using about about 90 minutes a week for the last month on my short nighttime commute and battery still seems strong so probably won't have to charge often or probably ever need to replace which was one of my initial concerns about a sealed USB charge battery. Multiple ways to mount this unit to my bike so great versatility there. Manufacturer should skip included jewelry type storage bag and include a way to easily fasten this great light to a backpack, pannier or clothing. Also, probably don't need all the many different rubber band lengths supplied although I can understand the need for versatility in application. Can easily use women's black nylon covered rubber hairbands to readily fashion just about any kind of attachment length needed. I would also like to see at least one waterproof hole through the width of the unit to secure it with a safety tether so it can't fall off and be lost. Just some suggestions for improvement...

The ONLY reason I am not giving it 5 stars is because on the box there is an option listed for a white light setting. No amount of button pushing produced a white light.The red light this light produces is very bright! I love the different combination settings. My bike is currently being serviced, so I have yet to use the light on the road. I should be able to soon. I also like the variety of attachment apparatuses. Strong rubber bands are provided in varying widths and lengths making attachment to virtually anything possible. Furthermore, a beatiful carrying bag, which I quickly repurposed, is provided to contain all the pieces.I have found the light to be exceptionally bright and useful with a strong attachment to my bike. The light is also well padded so as not to scratch my bike! I absolutely recommend this product to anyone looking for a sturdy, highly illuminating light to their bike. There's simply no way you won't be visible.Oh, and it charges with a simple USB plug!
