I had long been looking for an affordable alternative to high-priced camera trolleys looking. In Hama I then found it. I am very enthusiastic about the trolley. The build quality is super. The material is stable and the trolley function also acts robust. The trolley can also be very comfortable to wear as a backpack. Still, I would have a suggestion for improvement. One should offer the backpack still in a larger version, as this is almost too small for my needs. Inside is with me a 24-70mm, 70-200mm, Body 5D, two Aufsteckblitze, various accessories. The body is too high for the backpack with battery grip, since it is apparently designed for small bodysuits bodysuits or without battery grip. For reasons of space I can not store the camera with lens mounted in the backpack, since the Positon is intended is under the handle. Thus, every effort must be stowed separately. Therefore only 4 points. If the backpack a little deeper that the camera with battery grip would perfectly fit, I would give it 5 stars. Nevertheless, it is highly recommended.
