A Great Addition to My Recovery Routine
Quick note for new purchasers: the FluxGo’s come with small pieces of removable plastic both on the LED side as well as at the bottom where the charging pins are located. The plastic on the charging pins is there so they don’t charge / discharge the battery while being stored or shipped. They will not charge unless you first remove them. Second, the straps take just a little getting used to. However, if you make a point to keep the buckles facing up when you slide them onto the modules, you should be good to go (i.e., they won’t be twisted or refuse to slide into place). I’ve been using the Prungo FluxGo for about eight weeks, primarily for knee recovery, and I’m genuinely impressed with the results. I’ve dealt with knee pain and stiffness from years of sports, coaching, and general wear and tear. Since using this regularly, I’ve noticed less day-to-day pain, better mobility, and quicker recovery after being active. It’s not a miracle cure, and I don’t think it’s meant to be. What it is is a very effective recovery and maintenance tool. Early on, I used it daily, especially before and after soccer. Now I use it a few times a week or as needed when I push things harder. The portability is a big plus. The charging case and straps make it easy to bring to the field or use while stretching. An unexpected bonus is how versatile it is. Once my knees felt better, I started using it on other areas like my elbow after rock climbing, and it’s been just as helpful. If you’re active and dealing with joint or overuse pain, this is a solid addition to a recovery routine. Consistency matters, but the payoff has been worth it for me.
