If i'm not mistaken those are the red lasers that he sells on his website, so he made it not baught it and I'm pretty sure that's not the core.
As for the goggles it's one of the only things wicked sells that are actually of reasonable price.
Well it depends on how much you want to see the dot of your laser and wether you want sport style glasses or nerdy ones.
If you want sport style then you'd have to go with nova only you wouldn't be able to see the dot as much as you would with the lasershades, but the green lasershades don't come in sport style. :-/
Doesn't pointing lasers at their goggles damage the goggles? Think about it, those goggles are meant to absorb light of that specific wavelength, so won't that burn little holes in the protecting layer in the goggles?
