I picked up the RecoveryTherm Cube Refurbished and it works exactly as described. The compact size makes it easy to wear while moving around, and switching between cold, heat and contrast therapy is simple. I've used it on a sore knee and some minor muscle aches after workouts, and it really helps ease pain and reduce swelling. The refurbished unit arrived in great condition and performs like new. A practical, portable option for anyone dealing with minor injuries or wanting faster recovery.
