How can I compare the quality of different vibration platforms?
This is a difficult question because it depends on a number of different factors. The quality depends on the vibrations, the sound emitted by the device, its stability, durability and the level of user comfort, as well as the motors that generate the vibrations and other factors. A bottom-of-the-range vibration platform will, at best, provide a massaging effect. A vibration platform must be robust enough to generate powerful and regular vibrations when you are on it.
