CooSpo Bike Rear Light, Smart Bicycle Tail Light USB Rechargeable,Waterproof Bike Back Light for Cycling,6 Light Working Mode Options

I received this bike light about 10 days ago and am impressed so far.The unit seems well made of aluminium in a cylinder with control switch on the rear which screws into the bike mounting, I suppose this makes it waterproof.A quick 3 hours on charge and off and mounted on the bike. I have used the light every day and had it on during the daylight and early evenings switched on for between 55 minutes and 1 hour and 10 minutes a day.The light appears bright and obvious, three manual modes - flash, breathing and on. Additionally there is an auto mode which is supposed to switch off when not moving and instant on when moving with a light sensor too.I like the breathing mode best.The unit has a brake light function which has a sensor that detects the momentum change from forward to slowing. I have tested this and it works, maybe a tad sensitive but the extra flash of light is a plus in my view.Yesterday I thought the light was a little dim so thinking it was running out of charge left it running while on my desk. From before 10 am and it was still running at half past eleven at night so nearly 14 hours on breathing mode and it was still on and breathing. This impressed me no end so did the same today, except 9.45 to 6pm and still breathing away. I was obviously wrong about the dimming.The light is still in operation, brake function still in operation. I have not recharged it yet.I like the mounting, the base is screwed into the rubber bike tube mount and I am experimenting with a magnet mounting for my own amusement. Apparently there is a screw hole mounting available although I have not seen how to buy it. I would have preferred this additional mount to be in the package but in my opinion the sellers have priced it keenly in the bike mount marketplace.I am impressed and would easily recommend this and if I need another I would return here and pick up another.

I was very impressed with how bright these lights are! I've had these lights on my bike for about a week now on the highest power setting, and the battery is still going after the first charge! The lights were simple to install, took me less than 5 minutes. The lights are very well made and don't feel cheap or flimsy, I'm confident they will last a very long time. It's great to have a brake light, I feel much safer on the roads knowing vehicles can see me and when I am braking. I've shown these lights to some of my mountain biking buddies, they were also impressed with how much quality you get for such a little price. Brilliant lights!

not had it long so cant really say about the battery life ,but its working well ,would be nice to be able to check that the brake light is working as it should ,the only way is for some one to tell you or some one to ride bike so you can check ,apart from this its well made and locks into case well so should be water prof .

This is a really nifty light. Small and light, with good brightness, with useful flashing modes that just get on with making you visible.Charging is done by unscrewing the light from the base, but the unit is secured with an integrated rubber ring that will help protect against vibration effects unscrewing it. The micro USB charging works well, and suits me as I have loads of stuff that uses micro USB.The brake light is a nice feature, especially since my bike has Hydraulic Disks, so I cannot connect a cable like other brake lights.For me the feature I love the most was the saddle rail mount. Hanging one light and the mandatory reflector doesn't give you a huge amount of space for additional lights. Being able to choose to attach the light to either the seat post or saddle rails saved me having to reconfigure my rear lights. A couple of cable ties to secure the rail mounts got me up and running with this light quicker than I could read the enclosed info leaflet.Overall, I think this is a fantastic piece of bike lighting.

Wanted a bright rear light for cycling, so ordered this at a very reasonable £9.99. My expectations have been surpassed. Received a very well packaged and made light,with all the required fittings. Quickly charged it and put it on my bike easily.Couple of things I really like 1: the auto mode (there is a manual mode for continual light if preferred) which according to my co-rider worked well, coming on quickly in darker, more shaded parts of the road, then off again when not needed in sunlight, and 2: the brake light, which is a really cool - and useful - feature for such a low cost item.Light is very bright and a charge lasts long enough to operate on a decently long run.Highly recommended.

Well made machined metal, great breaking activation, I just wish it was brighter especially in day light.

Very bright light.Build is nice and sturdy given the cost.Automatic mode is good, I just leave it on all the time.Battery lasts a decent amount of time, flashes when it's running out so you have enough time to finish your ride and get home.I would happily take a bigger unit for a longer battery life between recharges however, it does recharge quite quickly.

I bought this last year, but unfortunately waited over 30 days before checking how long the battery lasted. This meant that I couldn't return it via Amazon. The battery life is about 2-3 hours rather than the claimed "up to 48 hours", so it needs unscrewing and recharging after practically every ride. Some friends got these at about the same time, so I know that some of the lights can last a lot longer.I contacted Gaciron directly, and they promised me a replacement which never arrived. And again after I chased them up.As for the light itself, it is not really bright enough, and is fiddly to unscrew for recharging.The moral is: check any bike light for battery life as soon as you receive it, although there are also a few reports here of the light failing after being used only a couple of times.

Compré 3 luces trasera para las bicicletas y se daño una (1)No llevo un mes con ella, no aguanta la carga, después de tenerla 3 horas conectada al cargador, el led indicador de carga completa sigue parpadeando, nunca queda la luz verde fija. La desconecto y la pongo en funcionamiento y al poco tiempo se apaga y vuelvo hacer la misma operación.La otras 2 luces funciona correctamente, hasta ahora. Saludos.

Très pratique. Peu encombrant et pas gourmand en énergie. Pourquoi s’en priver.Je recommande

Remplis parfaitement sa fonction 👌🏽

Au bout de quelques jours, ne marche qu'en mode fixe. En mode clignotant, il marche qqs secondes puis s'eteint.Où est le service après vente dans ce cas ??????Mieux vaut l'éviter.

Impossible de trouver comment la fonction de detection de freinage fonctionne !!!produit acheté pour cela...Documentation incompréhensible
