Number of programs
The number of individual work programs provided for in the design of the massager. Do not confuse this parameter with the number of speeds (see below): many programs provide changing the speed during operation.
The more this number — the more versatile the device, the higher the probability of finding the best option for each specific case. On the other hand, note that the specific range of programs may be different, it should be clarified before buying. As a result, it is quite possible that a model with fewer programs will be more suitable, while a more advanced device may not have the right options at all.
Number of speeds
The number of speeds at which the device is capable of operating. In many classic vibratory massagers (see "Type"), where there are no special programs, this indicator actually corresponds to the number of operating modes. Anyway, the intensity of the impact directly depends on the speed; which means that the more speeds, the more options to choose from. On the other hand, the specific speeds and how they are suitable for specific purposes, it still does not hurt to clarify.
Country of origin
The country that is the "homeland" of the brand under which the vibratory massager is released. Note that the actual place of production may be located in a completely different country; and the country of origin of the brand is indicated in order to make the product more attractive to the buyer. On the other hand, in the modern world, the quality of a product depends not so much on the country, but on how this quality is controlled by a particular manufacturer. Therefore, when choosing, you should focus primarily on the brand, and not on the country.
