What Buyers Like About The Quattro EMS IF

Buyers of this machine enjoy these features:

  • Clinicians love of this unit for its 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 patient lock and patient compliance monitoring ensure that each patient is getting the assigned treatment, and makes that treatment easy to record.

What Buyers Don’t Like About The Quattro EMS IF

For a therapist or 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.


The Quattro EMS IF unit is cleverly designed for therapy delivered in a clinical setting, with its adjustable settings and ability to treat two patients simultaneously.
