The Walimex Pro Beauty Dish (50cm) makes a nice light for portraits. Bit wailing on high level: the average reflection point can be clearly seen in the eyes of users, here are products of other manufacturers in the balanced lighting. These costs but also significantly more. The bowl 50 cm is perfectly adequate in size for individual portraits, the 70 cm would be me definitely too big!
For me as an amateur photographer absolutely great product at a fair price.
