This is my 2nd dyno LED lamp. The first unknown brand laché me quickly. This seems to hold on. I use it every day to serve as pilot to my 3 year old son. For those who have difficulty pressing the button on / off, I would just say that my son gets there without difficulty ... The lighting is good but not dazzling. Only complaint battery weakens rather quickly by lowering the brightness.
Update of 20/01: After 1 year of use, the battery of this lamp exploded during a refill !!! she came out of his compartment and ultimately to burn to the ground with flames 10 cm for several seconds. No injuries but a big scare for everyone. Conclusion: DO NOT BUY !!! RISK OF EXPLOSION. ps: I warned the manufacturer.
