OfrdncyBP for Home Use Rechargeable BP Monitor Wrist Digital BP Machine with Big LED Backlit Display, Voice Broadcast, 2 * 199 Memory Storage

It is small, it is easy to work with, it tells you the pressure with sound, it does not need a battery and it works for a long time with USB charging. Only the fabric material that is tied around the wrist is not of high quality and may wear out over time and frequent use. Of course, the brand that was sent to me was not Ofrdncy, it was vileco, but it looked very similar to the photos on the Amazon site, and I checked its accuracy with other pressure devices. Due to its small size, convenient use, high accuracy and no need for a pen bottle, I strongly recommend buying this type of wrist blood pressure monitor compared to the arm type.
