ThinkGeek Sonic Meeting Disrupter - The Next Generation of Pranking - Office Prank

Excellent little gadget

The item is what it is...very loud!!! The only draw back was that the batteries drain really fast. So be ready to replace them if you get it back in one piece.

Worked as expected, coworker I am sure would not give 5 stars lol

It worked once and then we could not get it to work again. Total waste of money.

Cheap. Doesn't even work. Was basically robbed.
