BOSO medicus smart semi-automatic blood pressure monitor, 1 pc

Unfortunately, this device was a bad purchase.It's very cumbersome to use and extremely sensitive, displaying an error message as soon as, for example, the cuff is even slightly too tight, too loose, or a millimeter off the mark.I thought it would get better with a little practice, but after struggling with this device for almost a year, my patience has run out.It's probably worth investing in something better; you can't expect much more for the price.
