I'm really glad that I took this high-power device. It is always brave and are nevertheless times larger inside. No problem. He has an enormous force. The guide will help very little. It is very poorly explained where you can see exactly how big the gap actually is when the roller rotates. In addition, one should the plastic panel can unscrew when he still clogged times. The screws that I see are all security screws which can only open the service. If anyone knows how to do it please email me. The device itself is supi.
