Well, let me say this...
This is the best peace of equipment that I ever bought.
I've been using it for 2 years now, for more then 200 live gigs, and it never failed.
What you get in this small, light and easy to carry black box is just awesome!
It has everything that you could possibly think of...only if you need more channels, but then you have other versions of this product.
So, you get all the channels you need, all the effects that you need, and then some more...equalizers, usb port, so you can reproduce music, or record it live...and one of the best things - everything is controlable with their app that you can download for free, on your tablet, phone, or something like that, so you can move around the place, and make the sound that you desire without running back and forth all the time. It's so small and convenient that you'll never think of carrying around any of those big, heavy pieces of equipment.
The only down side - there were some situations when the wireless connection was unstable, or couldn't make a connection. That happens when there are too many wireless signals in the area. In that situations you need an extra router so you can make a good connection. So, that's not really a big problem, if you can even call it like that...
All in all, this is a great product and I highly reccomend it!
