This is a really handy little wind-up headlight that gives lots of light. Although the headlight itself has to be removed from its base before winding, this is not really an issue (the aching arm from whizzing the winder might be more so!) and it clicks neatly back afterwards. The only quibble is that after six months of daily use the winder finally broke, but considering what I'd saved in batteries over that time - I use it for at least a couple of hours every day, sometimes longer - I felt that I couldn't expect a little piece of plastic to last for ever and that the saving in batteries and the torch's perfect functioning, including in the rain, make it well worth it, even if I have to replace it every six months. A really useful little gadget.
