Be sure when you buy this battery-guzzling piece of junk that you also invest in a rechargeable battery kit as well. This thing sucks the batteries EVEN WHEN IT'S TOTALLY OFF! If you don't use it for a month, your batteries will be completely dead. You'll need four AAA's.Hey, guys at TI: can you effin' fix this, please? Or are you a subsidiary of Energizer, Inc.?
