It charged perfectly fine on day one and two but by Friday a yellow light was blinking. I did “arguably” just as well with my Astro Mixamp. Hay momentos que después de 4hrs me molesta el colchón las orejas I bought it for 98$ and for that price it is really good. I also never had to worry about them moving around like the large hospital pads. The shoes take some getting used to, but they are comfortable. Wear it about 5 hours a day, , now my waist is smaller. Just be careful with it. It hurt so bad we did x-rays to confirm there was no breakage. I really like this easy to assemble and sturdy shoe rack.
