Recordable megaphone perfect for lazy protesters

Ever joined a public rally or protest? No doubt you would have come across people who carry hailers while spreading their message to anyone who is willing to lend an ear. The Recordable megaphone caters for folks who are willing to spend time at a protest, although they are not willing to stretch their vocal chords in the process. This device is powered by a quartet of D batteries that will last anywhere from 6 to 8 hours of broadcast time. In addition, a built-in siren allows you to attract attention before you play back your pre-recorded speech. Would you fork out $22 for this?
