Vorneweg - I have not even tried the device. This was not necessary. After I took it out of the box, even fell on a lot of scratches and small broken plastic particles rattled inside the housing back and forth. I once threw then a look at the reviews and because it was reported within the last day of a used and defective equipment. This makes always been a well-concentricity to all other purchasers.
It remains only to say: do not order from "Electric Fast Shipping"! These are only unnecessary shipping costs, which are a non-refundable.
