I have been a few weeks, the Mobile Sound system of e-Lektron. Delivery was fast and accurate. Connected, SD card and USB flash drive plugged in, then connected laptop with cable. Terrific sound for this price. 1 microphone did not work. Some would now be upset and not 5 stars. I give it anyway and for good reason. Wrote via e-mail that has broken a 1 microsecond or the connection. E-Lektron has sent me immediately in the shortest possible time with little effort, a new micro-which works perfectly. Even the noise of the microphones are actually negligible because when music is playing you can hear the noise no longer. If no music is playing, the noise actually not a big problem, because I want a system that's perfect, so I must be a minimum of 1.200, - count - - 1,500. The support has answered immediately on my mail and was very accommodating. I'll be the next few days more products of this company order (need this professionally for my rental) because I am absolutely convinced of those skills. So there was a 6 star I would also press this yet: o)
