I picked up the RecoveryTherm Knee Refurbished and it has been a great addition to my routine. The cold, heat, contrast and vibration options cover whatever my knee needs on a given day. It helps ease discomfort and swelling, and I notice better blood flow and range of motion after sessions. The refurbished unit works exactly as expected, which makes it a solid value. Setup is simple and it fits comfortably. If you deal with ongoing knee issues, this is worth trying.
