I used a Primus 500 Geha good 10 years. Unfortunately, the capacity was maxed out at two leaf, which is why I have decided to use the new device. The collection container is compared downright primitive, not reinforced upper margin, as I knew him; he just seems "cheap". Also, the device is considerably louder than I was used from above device it. However, the interface with the 4x40 mm is considerably safer. Therefore, a central vote> 3 *
