Totally agree with you. This is an expensive, 'cool' and a non professional toy.
Clearly it's not made to the real life of a professional musician.
Yes, sounds good... when it can sound. It's not enough by far. And I'm happy for those who tell that this is a zero problems product but wake up please, only few of you have zero problems. The reality is that this is a unrealiable and unuseful piece of gear if you use it for professional purposes... and even when not.
The other day I play in a very very small village, outside of it (I mean, very far from any WiFi hotspot you can imagine. Probably the nearest WiFi spot would be at least at 100 meters of distance from the stage), almost in the forest (in fact, we were in the beginning of the forest). The result? The most humiliating moments ever as a musician. I couldn't move more tan 1 meter from the receiver. I tried to jump out the stage, but once I did it, impossible to make it sound my guitar. The singer told me that in that moment he saw the green light in the receiver turned completely off when my guitar sound dissapeared. How can you explain that unless there are WiFi trees?
Maybe a faulty unit? Maybe, but then... almost every unit is faulty?
Moreover, it's incredible to receive negative points for telling only facts. I think the fanboys were only a thing of the videogames world and all that kind of things.
