The product seems to keep its promises. It is a bit difficult, but also very stable. However, I had to rebuild one of the mounting clips, as this was between the handle and the fastening device for Use tripod and not ready for it. So I could not clamp! During the reconstruction it could happen that the clip breaks. So be careful! Furthermore, the clips are not easy to use, as they have a strong suspension or not to be a good grip and also are quite "sharp". One should there be very careful, otherwise it can easily happen that you tear the reflector / diffuser.
