I have had several ND3's and have had to return them all. I have the Nite hunter 500 and the single mode green light and so far I am impressed. With my ND3 it had to be 95 degrees for it yo work Not so with this. After the first charging I have had to adjust it to make it charge correctly but so far this is the best multi purpose flshlight ever. Nite nite hogs.
Pros: Great flexibility between modules, great battery life, extremely bright for the weight and size.
Cons: Battery charger has gotten quirky and you have to play with the positioning to charge.
