I picked up the RecoveryPulse Calf for post-run tightness and it does the job. The compression feels snug without cutting off circulation, and the vibration adds a nice extra layer of relief for minor aches. I like that it's a single sleeve, so I can wear it on one leg while stretching or even at my desk. The germanium-infused fabric is a detail I can't really verify, but overall it's convenient for recovery on the go. Battery life is fine for a session or two. Solid, not miraculous.
