We bought this pretty little equipment to tour around the country with live shows. It saved our asses a few times. When we do gigs orgonized by others, they want to use their own equipment and most of the times they dont really have a clue how the system works. Sadly this happens a lot of times in our country. This was the main reason why we needed our own equipments, just like the Allen and Hearth wz4, wich is a reliable product, works perfectly, never even a small issue.
