The pen "just worked" when I got it. Looks good, nice design.
The batteries ran out very quickly. Bought new ones, they ran out very 
quickly. I guess the laser can drain the batteries in a minute or two, 
so one can't really use it much for pointing.

Do a laser need that much power, or is it just a simple design that 
lacks current limiting?

The third set of batteries didn't work well for me. conduction seems 
rather bad, perhaps this is fixable by installing some actual wires 
instead of relying on the casing.
