I have ordered the product due to the positive reviews from other buyers. It was worth it, this device is very precise, even for first time users like me. The handling is very simple, well explained Duch pictograms on the back of the package. Nothing more is needed as well. And that you should press the lever with force also true timid try could be rather disadvantageous here. The price is reasonable, the delivery took place within 2 or 3 days. This device I can only recommend !!!
