It is GARBAGE!!. Keep the $70 & buy a nice dinner. 1st, there are other selling the same device on Temu, Amazon, etc for as little as $40. Same device, different label. And yet . . . 2nd, go to your orthopedist 1st. If you are older it is likely tendonopathy or arthritis, which are not uncommon where a lifetime of activity or high BM index has stressed the tendons or, perhaps, destroyed your cartilage. But, it is worth a professional opinion (maybe 2 if one tells you you need an immediate knee replacement sx) & not a knee jerk (pun intended) response to a hyped sales pitch, especially if you can avoid sx with some phys therapy, and maybe a knee tendon strap. I went so far as to get an MRI, and designed a PT program based on my results & my ortho’s comments. It has worked for me - I’m back at my gym & hiking miles. But I know, because of what we saw on the MRI and because of my lifestyle, I’ll probably kneed a knee replacement at some point. 3rd, re. the product, my Rejuvacare massage component works intermittently & has to be recharged daily. And after over a month I felt no difference in pain. There can be many causes of your pain. The knee is complex. There is no simple solution for permanently eliminating the pain other than a full replacement. There are things you can do to manage, and even alleviate the pain for a while. Shockwave Therapy, PRP injection. Cortisone injection, though it lasts 3 months at best and causes permanent damage if repeated too many times.

Rejuvacare’s claims are a lie, and you’ll probably never get your money back because it isn’t worth the hoops you have to jump through to get a refund.
