Don’t waste your money! Just another cheap Chinese product!
USB-C cable too short & the one I got only charges on one side of the USB-C end. Left it on charge for 12 hours, kept indicating ‘charging’. If I flipped the USB-C around, it shows 100%. Kind of a sucky thing!  POOR QUALITY CHARGING CABLE!  I would rather buy batteries!<br /><br />Also, the longer I have had it the slower it reads oxygen and pulse rates! ANOTHER reason to not buy this product!!<br /><br />Can you say RECYCLE? Plastic into landfills??<br /><br />After reading the papers that came with it,<br />THERE IS NO rechargeable Battery replacement procedure<br />AND this product is good for only 800 charges. YES, that is a large number, but IMO,  for the price, IT COULD HAVE A BATTERY REPLACEMENT.
