I've been using the RecoveryTherm Knee after runs and it's become part of my routine. The cold and heat settings are easy to switch between, and the contrast mode feels great on tired joints. I've noticed less swelling and stiffness, and my range of motion seems better. The vibration is a nice bonus without being too intense. It fits comfortably and stays in place while I move around. Solid pick if you want one device instead of juggling ice packs and heating pads.
