We were looking for an affordable blood pressure monitor and this exceeded our expectations. It fits my thick arm successfully. Also, it has big and clear numbers are shown on the APP which made my parents very happy. It has great accuracy and the most important thing for us is rechargeable, the specs say it can charge for 1000 measurements.
I searched long and hard for a lightweight BP monitor before I found the AirBP. This is exactly what I need for my travels. Most BP monitors I found were about a pound or more which adds a lot of weight to baggage especially if you are flying an LCC. The AirBP uses a unique system where it uses its app on the mobile phone to measure the readings. This cuts down on the device needing its own display - and in AirBP's case, cuts the weight down to about 1/3 of a pound. The screen on my previous BP monitor broke during transit in the bag, so this is no longer an issue to be concerned about.
The mobile app is manageable - nothing fancy. It shows the reading as it's measuring your BP, keeps a history and chart of past readings with notes and names, and allows you to export the data. Additionally on iOS, you can connect to Apple Health if you wish. I had no problems with the connection from the device to the app on the phone. It activated very quickly every time. And the device has a rechargeable battery built-in with a cord included. The cuff comes "pre-curled" which I assume is to keep the cuff wrapped up small and transportable. This might make the cuff around your arm a bit snug in order to fit, but seemed to work fine. Note that my arm diameter is probably a normal size. The reading seem to range some just like my experience with other home/personal BP monitors so in this regards it did not seem better or worse. Occasionally, it seems to reset while starting the reading. Again, this is normal in my experience with other home/personal BP monitors. Though it does seem to do it slightly more.
All in all, I am very happy with the device after a week of use. I would recommend if the priority is something compact and lightweight.
