I don't care whether it looks like a lightsaber or not (although it is pwetty...besides, the company knew exactly what they were doing and just thought they'd see how long they could make it sell for before LucasArts threw a wobbly), but I do find the power a little iffy. I mean, 0.5-1W is a lot of power for a damn laser pointer, and it's a more dangerous wavelength.
Now, don't get me wrong, I love me some lasers (my PhD is in lasers after all, I spend my days surrounded by Class IV lasers way more powerful than that toy), but in general terms, the idea of the usual idiot who is like 'Pah, laser pointers are harmelss, haha, lok, it's in your eye!!' having access to this sort of thing (popularised by the lightsaber thing) gives me the shivers. This laser could actually (and quickly) do serious damage to someone. Including cancer this time, since it's a blue laser not a red or green one.
