Koogeek FDA Approved Smart Upper Arm Blood Pressure Monitor

I bought it, it is quite reliable, but I compare it with the professional, there is still a lack of work materials, but the price is very affordable.

Let's say I would only recommend it if you get it with a good offer. Sometimes it is disconnected from the mobile, although as a rule it is better than other devices of the brand. The fabric that brings to take the tension in the arm has been fraying me so the materials are not very good. At normal price, nothing recommendable.

The best one I have so far. But linking to my iPhone is sometimes cumbersome.

Whether it's a smartphone or not, it's very easy to use, and it's very small to travel or carry around, no battery charger to charge, suitable for all needs.

It seems to be of good quality, similar to my expectations, and the most important thing is to measure the tension and use it very well.
