Here's a fun product.
Nothing complicated, no batteries, nothing to plug in.
Works on the plain old megaphone principle...low tech.
Great for a trade show, recruitment fairs, schools and colleges.
Sometimes plain, simple and fun works the best.
These are on special at $1.99 each but only till the end of October. Fits the following iPhones: 4S,4G,3S and 3G only.
