Update: the seller has been really helpful by offering a choice between a refund or replacement light. After checking alternatives light I decided that this was still the best light to get for the money and requested a replacement. Very happy with the service so I've changed my rating from 2 to 5 stars. Original review: Good product, worked as advertised for 11 months. But I took it out for one ride when the roads were considerably wet and it broke. I've tried drying it out but it still won't work. Would've been 5 stars if it was more waterproof but I wouldn't recommend with this issue.

I have two of these lights attached to either pannier or top box on my BMW R1300GS. They are brilliant. I'm completely confident that they are waterproof, as I've ridden with them through prolonged torrential downpours. I get a good 5 hours out of them on their lowest brightness setting. As good and more flexible than a £500 set of Denali's in my opinion. Never had a problem with the rubber mounts, I've just fixed them permanently to the bike with cable ties for security purposes. I've never had a problem with them. And I've never lost one, even after days a motorway speeds.

I really wish I had read the user reviews beforehand. It seems I’m far from the only one who’s had issues with the quality of the mounts and the lack of customer support. The light itself is excellent: bright, full of useful features, and clearly well-designed. Unfortunately, all of that is let down by a mount that’s cheap, poorly made, and simply not fit for purpose. The Trek seat mount broke after just a few rides over two months, it snapped clean off without warning. I didn’t even realise until I got to work and found the light had fallen off somewhere on the roads of London. To make matters worse, the standard mount doesn’t fit aero seat posts properly, so that’s not a backup option either. It’s incredibly frustrating. For a brand that makes mountain bike lights, you’d expect much more durable mounting hardware. Until they address this flaw and improve customer service, I’d strongly suggest looking elsewhere.

The best rear bike light I have ever had. Super-bright. Different settings. There is an option to leave the main light on, and a flashing light below that lights up the road behind the bike. It's a really good idea. Solid build, quality light.

I've got through a lot of bike lights and this one is bloody brilliant. I use it road riding. I love the downward facing LED. It lights up the whole back of the bike and road behind you. I think that really helps you to be seen from the side. I like the small form, it's not too heavy, and seems to be well made. It's survived the winter with no obvious problems. Battery life is as advertised.

I've been cycling for almost 30 years and this is the worst light I have come across in terms of settings. The settings are utterly confusing and impossible to work out whether it's in a day or night mode and whether it's high or low flushing. Totally useless. Somebody once said "keep it simple, stupid". Clearly the designers of this light have never heard of it. The worst thing about this light though is it's battery life. All the reviews are praising it with an exceptional battery life ... well that was not the case with my light. The light did not even last 3 one hour rides without needing to be recharged. On the third ride it simply stopped working after 15mins, which was extremely dangerous as it was pitch black. All in all it failed on me twice. Before the ride it showed me green light, indicating more than 20%, but clearly that functionality doesn't work either as it totally stopped working after 15mins. The only half decent thing about this light is that it's well made and feels solid, but I I don't need a good looking light, I need a light that works in the dark!! And the above wasn't just my experience. My friend and I bought it together after being convinced by the reviews, and he had exactly the same experience. When I wrote to customer service, they re-directed my query to another department and the trail went cold. No response since then. I am not sure which light were all the other positive reviewers using, but that was not our experience.

This light is amazing. It has several light modes for the intensity you need at any given time. Once you have it installed on your bike, the removal and reinstallation is fast and easy. I have an aero seat post and the fit is perfect. The fit is very universal and so far the water resistance has worked perfectly. This light seems as it has a very strong and durable housing and is very well made. So far I am extremely happy with this unit. I highly recommend it. Compared to other high end named brand lights, you definitely get your monies worth with this light.

This light has some very opinionated design decisions in the software, and to the product folks out there....if you're gonna be opinionated in your design, you're gonna get opinionated reviews. Buckle up, 'cause it's gonna get a little rough. The tl;dr: Excellent hardware that forces high power consumption on you, whether you want it or not, so that instead of up to 11hrs of battery life, you get 2-3 when riding in darkness. (And yes, this is a problem - I don't want to have to charge the battery every single day.) On the plus side: USB-C charging, excellent battery capacity; good battery life* in the mode I use most frequently; many modes; mode memory; quarter-twist mount. Now for that asterisk on the "good battery life": What I want out of a bike taillight is something that flashes stupid-bright so that the doofus in the car coming up behind me looking at their phone has something catch the corner of their eye and get their attention. And this does have an excellent daytime-bright flash mode. All good so far. The problem, though, is that once it starts to get even the slightest bit dark outside, it switches to this mode where it pulse-glows out the back and shines a bright red light directly to the pavement. At no time in my life have I worried about being hit by a car coming at me from below the surface of the pavement. I get that "provide visibility from the side" thing, but guess what - you extend the lens around the side of the housing a centimetre or so and that 300lm flash (that you turned off in favour of some slowly pulsing glow) gets people's attention. "But it's too bright at night", you say? Impossible. Nothing is "too bright" for a bike to get noticed, particularly when it's red. Goal #1 through #20 is "get noticed". So, not only does the light go from a bright flashing "HERE I AM!!!" flash to a dull slowly pulsing light is that there's now TWO LED'S soaking up battery power, so the runtime of the light goes from 11hrs to maybe 3hrs at best. Yay (insert sarcasm emoji here). And if/when the battery does run low, instead of doing what it can to extend that runtime by....you know,....GOING TO THE FLASH MODE THAT LASTS FOR 11 HOURS, it instead glows even brighter so that you notice that your light is running low. Which....ok, great -- the light let you know. But what can you do about it for the remaining hour of riding until you get home...? Nothing. Just accept the fact that your light is gonna go out sooner than necessary. And then it has a brake light function: In theory, you hit the brakes on your bike, and the light shines brighter. There's no wire/sensor like there is on a car, of course, so it has to rely on some electronic sensor. So, I realize this isn't easy. But come on: If you're riding at like 35kph on flat road, peddling at 90rpm or whatever, if your speed varies between 35.8 and 35.5....the brake light should not come on. And yet it does - again just absolutely KILLING the battery life. The best part of all of these "features" is that MagicShine makes absolutely none of it configurable. If you WANT to just keep the low-power super-bright flasher going once it gets dark (and by "dark", I mean roughly half an hour before sunset on a clear day - why?!), instead of the light switching to the highest power consumption mode, well, go buy another light. Because this one won't let you. So I did. In short, this is a great light with TERRIBLE software.
