Now have the 3rd unit from this manufacturer, all have in common that they are very noisy. The unit was very well packaged. For a device in this price class, the contents of the package and the general. Condition is very good. Bit fiddly it is anzuschliesen hose. I DESN tube by means of a self-made tube then connected to my Kärchersauger and fixed with Stage Band. I recommend a vacuum cleaner with eingauter outlet to take and fix the power cable with cable ties to the hose. I bought the recommended abrasive mesh well. My tip: do not press too hard yes, let the machinery work. I have now ground to the device 200 m² drywall. Conclusion: For the price, the device meets my expectations in every form. It is highly recommended and can be up to the volume (on the other hand, there are hearing protectors) to compete with the expensive brand appliances.
