I go camping quite a lot and these lights are a godsend. So simple to use, run on AA batteries and are very bright. There is also a dimmer option as well as the sos feature.
Having the wrist strap and carabiner hooks as well is such an excellent idea as it means you can go hands free but still have light. I would recommend these to any keen traveler and in a pack of 4 the family can have one each
