I have a Blaze light with the green bike laser and ride the NEPN each day. Save your cash. It took 3 full days to charge and after 30 minutes, started indicating that it was running out of power. I kid you not. The green cyclist light is also barely able to be seen because the light is not remotely steady enough.
Also, it is _constantly_ changing the 'normal' light to flashing mode, which I hate. Today on the way home, it did it 3 times in the space of half an hour. I will be getting shot of it when I replace it at Christmas with something that doesn't have the green cyclist light gimmick.
(Alternatively, maybe I'm just one of the unlucky people who got the light as part of the Kickstarter project, and thus I have version 1.0, which is/was bound to be terrible.)
