Breg offers three different cold therapy units:
Polar Care Cube is a standard, generic model. It uses "wrapon pads".
Kodiak is a step-up unit that uses "inteliflo" pads that deliver more precise temperature. But the Kodiak also offers an optional battery pack to allow it to be used away from electrical current. The battery pack uses AA batteries
Polar Care Glacier is similar to the Polar Care Cube but has a larger ice/water capacity. It's size allows it to work with two pads at the same time. This is ideal for patients who have double-knee replacements.
