It is very good, get it. It also has a mobile application that stores 500 memories with dates and times to send them to your doctor.

Excellent, readable and user-friendly.
The quality seems very good, the feel of the main button is... somewhat like having 3-4 OCDs combined inside you.
It surprises me that some consider it a no-name brand. Times have changed. Braun is one of the oldest electrical companies, once one of the most glorious, and certainly the one that gave the most importance to design.
I confirm that it connects to iPhone/iOS, but it requires the Braun app. After measuring, it automatically transfers the results to Health.
It has 2 wristbands depending on the size of the hand, but one can also see them as replacements

Fast and reliable measurements. A great advantage is the connection with the corresponding application, which allows access to your measurements from your mobile phone as well as sharing them.

I do not usually write reviews for products, but I liked this one so much that I made the effort. I have had it for 2 days, so my evaluation is not based on long-term use that would have shown its reliability. I will confirm and amplify everything that the previous reviewers have written. For the money you buy it, at the time I am writing my review, it is an excellent value for money. The screen is very user-friendly, the repeatability of the measurements is so good that you think it somehow "cheats", the functionality is fantastic, the usability is exceptional, the case is the best (especially for this money), and the application is also excellent. I could not imagine a better or more functional application. The incredible bonus is the 2 wristbands (which seem to be of excellent quality) included in the package.

Soon I will order a second one for work.

Very good and technologically advanced.
The main thing: it takes accurate measurements, tested compared to doctor's measurements.
Otherwise, the Bluetooth and the corresponding app are good, so you can store the measurements on your mobile or on Apple Health, for example.
Also, it is comfortable and economical in operation. It does not inflate under high pressure and then drops until it finds the real one. It takes many small steps, so it does not exert much pressure. The experience is pleasant.
It is a good value for money. For the same features in other branded Japanese blood pressure monitors, you have to pay significantly more.

Very good, beautiful, with two straps which is very important and with an application that you send the results to your doctor.
