I was visiting there last November. Saw a lot of the same cheaper laser pens and gadgets at Temple Street and Stanley Market. Nothing too exciting laid out except for this one 405nm (I assume) pointer style that was priced about 1200HKD at Stanley. Visually it was only slightly less bright than the 30mW (confirmed on a LaserBee) green laser that I bought and it burned through a black plastic bag almost immediately. In hindsight I should have tried to haggle on it. If only to measure it's actual output.
Note: the batteries that come with it are crap as you might guess. Use them until the laser dims, then make sure they are the only batteries with your laser when you go home!
