O-Like NX-50P 250mW Red Pointer Review

My O-Like laser stopped working, it's a strange problem, i've used this pointer for about 10 or 15 minutes in 6 month, yesterday i've turned it on and after a little shake the dot has become a line ad have decreased the power, i've changed the battery but nothing change.
