What Buyers Like About the Quattro EMS Clinical Unit

Clinicians enjoy many of this machine’s features:

Chief among the favored features of this unit is the ability to treat a pair of patients side by side. This capability expands the options within a clinic, doubling the patient treatment that a therapist can accomplish in any given block of time.
For an in office machine, this model is surprisingly compact. It may lack some of the portability of models with built-in rechargeable batteries, but in point of fact it can easily be moved and used in any location with an AC outlet available.
The controls of the machine are simple and easy to use. Operators do not require a great deal of training time.

What Buyers Don’t Like About the Quattro EMS Clinical Unit

For a therapy practitioner who operates in a mobile setting, this machine is more cumbersome and less portable than some alternative models. However, it is an optimal performer in the clinical setting for which it was designed.
While it may not be the best choice for a therapist who will be called upon to work in arenas like the sporting field, it is relatively compact in comparison to many other in-office models.
