I bought about 2 years ago this device. After one year, the unit was broken. Anscheindend this product line had problems with the board. At that time my complaint was not answered and exchanged the instrument. One year later, same problem. Korridert board. The machine again made no peep. But this time stayed countless experiments with the manufacturer to contact inconclusive. I wrote messages on the website and directly from the Mail program. I called several times. All without response. Phone no one takes off. I do not know what's going on. Maybe the company is in bankruptcy. Because of the susceptibility to defects I would anyway strongly advise against the purchase.
