I bought this item for over £9.00. It arrived on Friday last, very quickly and following on from another person's experience, I wound it up for 3 minutes and placed it into my 7 year old's bedroom, who is a bit frightened of the dark.
He went to bed at 7:30 and whilst it was only functioning with 4 LED's, rahter than the options for 8 or 12 LEDs, at 7:00 this morning, it was still glowing fine. At 8 and 12 LED's it is a bit too bright as a nightlite, but to be honest, this is a camping light, you can read by it fine using 8-12 LEDs but it is not that bright but what do people expect? It would be more than adequate to get undressed by in a tent and would suffice for use by an individual to read by. If on the other hand you are looking for a bright light which will ight up an area say for 8 - 10 people sitting around a table, buy a Coleman lantern at about £50 and produce a bit of carbon!
I would wholeheartedly recommend this light for those people who want a cheap, safe, economic and environmentally friendly lamp with limited but useful ight output. I will try it out next week at my son's scout camp and if it remains as good as it is now, I will buy another.
One last thing, if you don't want to crank the handle like an adolescent for 3 minutes, there is an option of charging it up via a 6v charger,
