This light (and its twin rear light) is fantastic - blindingly bright if you look directly at it and yet it fits in the palm of your hand. The diminutive size coupled with the simple wrap-around method of attaching the light to the bike mean it takes seconds to put the light on or take it off and it can be popped into a coat pocket. USB charging is a great idea.

For the size (and price), this is an amazing product. It looks great, takes little room in your bag, can be put on and taken off in seconds, and does a good job. Its great for avoiding getting caught out without lights and would be fine for use on roads where there is some additional lighting. However, on my route home, there are some very dark rural roads, and I find I have to cycle quite slowly as I can't quite see far enough ahead to avoid the many potholes on these roads. It doesn't help that I find I have to angle the light quite far down to avoid getting blinded by glare coming up from the front edge of the light: it would be nice if this had been masked by the silicone housing. But on the whole, I have no regrets buying this and would certainly recommend it to friends.

Update: the above was true until I had to recharge the battery. There is supposed to be an LED that comes on to tell you when the item needs recharging and when your are recharging it, when it has been fully charged. This light never came on and despite leaving it for at least four hours, had clearly not done any charging at all as the light then went off on the next use. It now does not work at all. Unfortunately, since I bought this in the summer and have not used it very much, it is now too late to return it.

Shocking pink version for my wife's bike (her colour choice!) to march the more subdued black version on mine. rechargeable is great feature, light bright enough for commuting (which is what I bought it for) hence 5stars

If you must have lights that are not permanently attached, this is about as good as it gets. East to attached, bright and rechargeable - and the translucent case diffuses the light even further. Brilliant.

Brilliant they are... Bright and easy to mount and dismount. I bought two of these for my motorbike as additional lights for motorway and they even fit on the side mirrors' bars. They resisted a speed/wind at 120 mph... enough said. The battery lasts long enough, can't complain.

Rear and front bought. Rear developed a fault within 18 months (five uses) and front within a dozen uses. Absulutely pathetic build quality but the immediate impressions before they are used is very favourable. Give them time before reviewing because they fail quickly.

ideal as a 2nd light but a little distracting as you can see the lip of the light which can shine in your eyes when looking down. charge on computer and holds well. Can fit and remove easily onto handle bars

Great light and surprisingly powerful given the size of it. Of course, these are not recommended for illuminating your way in pitch black but they are perfect of urban cycling at night and in fact do a pretty good job of advertising your presence on the road. USB charging is the best thing about these lights though, no more batteries or dodgy dynamo lights for me!
