Really valuable instrument, with lot of options for the price. A single BIG defect, luckily quickly solved googling around: the touch screen responds randomly, sometimes by its own, sometimes not reacting to taps. I discovered that the plastic box is slightly thick and "pushed" the touch screen on the side. Putting four plastic washers between the two halves of the enclosure at the screws and screwing back all, solved the problem.
