Looking for Recovery Gear

After joining a weekend sports group, I've been dealing with sore knees and stiffness after games. A friend suggested trying a massager designed for athletes, but there are so many choices online. If you've used one that helps runners, CrossFit athletes, or football players recover more comfortably, which would you recommend?

That weekend sports group situation hit me hard when I joined a pickup basketball crew last year. My knees were so stiff after games I could barely walk home. Tried ice packs and stretching but nothing really clicked until a CrossFit friend told me to get a knee massager. Started using one after every game and the difference was night and day. The heat plus vibration loosens up the stiffness immediately and I recover faster without that deep soreness hanging around. I got mine from knee massager because they had the original model with real heat therapy and adjustable vibration settings, not some cheap vibrating wrap that barely warms up. Used it for 20 minutes post-game consistently and after a couple weeks my knees felt way more resilient. For athletes doing any kind of running, jumping, or cutting it honestly became part of my recovery routine like stretching.
