Wireless Calf Massagers w/ Compression

I purchased these because being disabled on oxygen 24/7, I must spend my time confined to my bed. That causes my legs to swell and increases the risk of blood clots, so the last time I was hospitalized they suggested that something like these would be a good idea. I decided to try it and opted for the cordless version so I didn’t have to worry about more cords getting tangled up, with the oxygen tubing and the cording for the nebulizer. Not to mention having to avoid all of these when they come in to help me stand so I can use the bedside potty. After they arrived we read the instructions twice to be sure we used them correctly. They said not to use them for more than 2 twenty minute sessions so that’s what we did the first time. I noticed that the control panel is located in a very odd place. When you have them on the panel is on the inside of your calf at the top so you either need to sit or lay with your legs apart or the are constantly banging into one another every time you move your legs. More than once it turned the units off and I would have to start over. Unfortunately we could not get it to allow us to pick less than the 20 minutes so we had to watch the clock carefully and turn it off when it reached the original time. The second time we had issues getting it to even turn on and stay on. I made sure not to move and it didn’t take long for my right leg just above my ankle to start feeling much warmer than it did the first time. My husband adjusted the temp till it showed the lowest setting and I did just 1 twenty minute session. When we took it off the area where it felt so warm was bright red. We didn’t think anything about it until the next morning. My leg was screaming in pain and that area was now purple looking. Fearing it might be a CVT we called for an ambulance. When it arrived the EMT agreed that it looked like a CVT and they transported me to the Emergency Room. Once there they did an ultrasound of both my legs and cleared me of a CVT, and instead diagnosed it as a 1st degree burn. By this time a large blister with a smaller one just above it had formed and they were both full of fluid. They lanced both to drain them, cleaned it with an antibacterial and covered it with a breathable clear bandage. I had to take antibiotics and keep the dressing clean and dry for the next 10 days. I now have a scar and a dark patch where the burn was. We contacted the seller and was told we would get a return sticker in the mail so we could send it back. We waited all through April and heard nothing. I again contacted the seller and they said they would send me another return sticker. I asked why can’t they just send me a QR code we can just show them at UPS and they told us they don’t use them because they had so many issues with readers not sending it to the right location. It is now May 22, 2025 and when I contacted them again today, I was told the RETURN WINDOW WAS NOW CLOSED, It closed on May, 9, 2025. So we are out $89.00plus tax . This is GARBAGE! DO NOT WASTE YOUR MONEY! And the funny part…now I see AMAZON has a notice on the product page for these that says…most people return this product! I woukd like to know how they did that?
