In principle, the Saxholder's a great idea: not to let the weight of the instrument rests on the neck, but on the shoulders. However, the shoulder pads are not real cushion. It is, rather, a rib-like and rather hard plastic encapsulation of aluminum rods. If the Sax depends on the holder, the pressure on the shoulders after some time, a realization uncomfortable to painful, as well as everything it is bent does not help. In this respect I would like to see here as improving proper padding in the shoulder area, for. Example of this thermoelastic Visco foam, then the Saxholder would be perfect.
