I had a few flashlights that I used in my work. This lamp has exceeded my expectations. It has three functions. The change of these functions will also be operated via the on / off switch. Very bright and easy to use, but the charge time seems a little long .. Anyway, it is very efficient.
Supplement 2015.3.17 Very satisfied with my first purchase (s1). I bought another (s2), it is also very good .. PS: S2 is larger
