In observe, the SKG OS500 Hand Massager excels as an on-demand aid station for drained fingers. The unit gives multi-point therapeutic options, using air compression, heating or cooling, and therapeutic massage rollers working in sync. The system options six completely different pre-programmed patterns and intensities. Throughout testing, all of them proved equally efficient at restoring blood stream from the wrist up, with the three-level warmth setting working particularly nicely to loosen up deeply cramped hand muscle groups. The built-in cooling fan can also be a welcome addition, guaranteeing fingers don’t get overly sweaty throughout longer 15- or 20-minute periods. Whereas the palm therapeutic massage rollers had been efficient at working the muscle groups, it will have been good if in addition they moved forwards and backwards. As an alternative, one has to depend on barely shifting one’s hand contained in the unit to get the rollers to work nearer to the wrist or simply below the fingers. Except for this ache level, the unit carried out nicely as is, and the battery life was first rate, with USB-C charging.
