Episode 2 - Philips mains tester screwdriver

I found the Philips mains testers just a few feet from where I live now. The price is so low that the shipping fee will definitely be higher then its value. Thus I decided to sell them in the quantity of 30. So the bid winner may resell them or do whatever he/she wants. I have checked the price in US, and the retail price is about 10 times higher than the price I can get here.

It is basically a voltage detector which lights up when contacting something has a higher voltage than the ground. This is the spec I can find from the tag.
Detect AC voltage from 100V to 500V against earth.
Dimension: 3.5x120 mm

The listing is here now. http://cgi.ebay.com/30-x-Philips-mains-tester-screwdriver-voltage-detecter_W0QQitemZ170224206635QQihZ007QQcategoryZ42341QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Only 3 days left, but I have got 0 watcher. It seems nobody wants them.
