Did the keyboard for just over a year in operation, then bought bem electronics trade with the blue C. The keyboard was meant to play mainly or tap in low lighting. Positive is the perfect design. The lighting is not too bright and also appears on the edge of the keys hardly. The keyboard size and layout of the keys is perfect. and compared to mechanical keyboards, the stop is rather dull and quiet. Is very good that the keyboard the press participates many nearby keys, not self-evident in the price .. Negative are the keys to the knaatschen a bit, especially if you do not meet exactly in the middle. This comes from the rim of the keys. The longer I have the keyboard, the more falls on the, and the more it sucks. Schreiber with touch typing is likely the extremely disturbing. Otherwise, the quality is good no dropouts, etc.
