I get one of these issue at work today because I could not find my normal use flashlight . I throw out the box immediately so I have to look up the multus mode feature online to clarify why the light be do what it be do . I really like these feature though . the 25 % brightness feature will help if you want to use the light in candle mode as the bare led be super bright and not suitable for light a table if the power go out . less bright equal more comfort in those situation . I can see myself use the flash feature as well . you could leave the light outside flash as a signal if someone be go to you house and could not find it , for instance . the SOS feature be a neat thing , I suppose , but I hope I never have to use it ! I have a mini mag aa at home with a lead conversion , but this one be much brighter . same mag quality you expect from they other stuff . if I have to buy this light , I certainly would . I be glad work give I one for free -lrb- go toolroom guy ! -rrb- but I want to recommend this product in case anyone be on the fence about it .
