Ossur has two main product offerings: the "full" version offering is called "Ossur Cold Rush" and the "mini" offering is called "Ossur Cold Rush Compact". 
 The main differences are the size, power, and ice capacity.
  • The Cold Rush is physically a bigger unit, it has a more powerful motor and it container can hold more ice. So if you want to have a long cold therapy session, consider the Cold Rush. 
  • If you are looking for something that is smaller, more portable and you need only a short duration cold therapy session, the Cold Rush COMPACT is probably the best unit for you. 
  • Both units take the same pads and are interchangeable which adds to the convenience if you already have either unit.
