Keywell Rear Bike Light - USB Rechargeable Bicycle Tail Light with Super Bright 30 LED and 6 Lighting Modes- Easily Clips On as Red Bike Lights for Mountain Road Bikes Safety

This appears to be exactly the same item as identical looking lights under different brand names and this one is the cheapest.You get the light with a separate rubber gasket, 8 rubber bands (2 of each size) a USB lead and a rather nice fabric bag to put it all in. The bag is an especially nice touch as it prevents the lead and bands etc. from being mislaid (other manufacturers take note!). The bag is actually big enough for my front light too, so I now have all my cycle lights and their accessories in one handy little bag - Perfect!I was slightly put off, at first, by the mounting method - it is simple and relatively foolproof but the simplicity means that there is no option for tilting the light relative to the angle of the tube - it has to be mounted in-line with the tube. In practice, however, this has not yet been a problem. The light is painfully bright at the maximum setting (eats equivalently priced lights for breakfast!) and the viewing angle seems wide enough that the slant of the seat post does not cause any real issues.Overall, when you consider that this is very similar to a light made by CatEye which retails at 3x the price, it is very good value for money.Observations on the mounting method:1) I didn't like the fact that the rubber gasket becomes separated from the light every time the light is demounted: I was worried about losing it, so I put a couple of dabs of super glue on the pins that connect the light to the gasket - problem solved!(make sure you don't get any glue near the USB port! - one end of the gasket has to be free to lift up for charging)2) If you break or lose the rubber bands - you could just replace them with the appropriate size of 'O' ring (readily available from here and most hardware shops)3) CatEye make an adaptor for their very similar light which allows it to fit their standard bracket (£1.99 for the adaptor, £2.95 for the bracket) and as far as I can see, their adaptor will also fit this light. So, for an extra fiver you can have a mounting system with tilt adjustment and you will have spent only half as much money than if you had bought the CatEye light without the adaptor!I have only owned this for a few days, so can't yet comment on durability but it seems pretty solid

Great light, but the rubber rings used to attach to the bike perished after a couple of days. So now I have a great light with no way to attach it to my bike.

GOOD - very bright light, discrete. Good battery life between charges.BAD - lost the fixing bands within days and the rubber backing bit a few days later.UPDATE:- The vendor contacted me and sent me a whole new item even though I only needed more rubber bands. You can use normal rubber bands to attach it to the frame. A very nice gesture - very good after sales service. If you put a bit of glue on the rubber backing it stays in place on the light. A good safe light.

OK light. The backing rubber has to be removed for recharging, so whole thing has to be demounted. Held on by a lacky band which is bound to break eventually and the light will be lost.

Very bright ,the battery lasts a long time before next charge, definitely be seen with this amazing light, and easy to use,

Good product but I was a bit disappointed with the battery life. My previous light lasted for ages but this one only did a few (longer) rides before I wasn't sure it would last

Great little light, lots of functions & nice & bright!In addition, customer service from Keywell has been fantastic, highly recommended :0) x

Was great until it just stopped working after two months. Charges up but won't turn on.

Je les ai installé sur ma trottinette xiaomi m365 pour être mieux vueElles ont une très bonne autonomie et elle éclair très bien même au niveau le très faible

Faro perfetto da montare sul tubo sella, che rende visibile il ciclista e con batteria che garantisce una lunga durata. Ha patito un po' di infiltrazioni d'acqua sotto una pioggia intensa che non ne ha pregiudicato il funzionamento.

Le seul problème est qu'il Est assez encombrant et j'ai dû essayer plusieurs emplacements avant de trouver le bon.( directement sur la tige de selle. Sinon RAS , bonne qualité et autonomie très suffisante
