Not the most fashionable device, but works well and reliably.

This device was surprisingly loud and worked perfectly.

Excellent device!

This is a very cool, affordable little device

Easy to use, great device

Didn't get quite as loud as I hopped, but saved my voice so that I wasn't hoarse after a full 4 day weekend running RPGs
