Connectivity con telephone es Buena y quality.

I just bought the KealthTech TK26 smartwatch, and it's amazing! With just one click, you can micro-check the health of the five major organs, including blood sugar, blood lipids, uric acid, blood pressure and blood oxygen. The functions are really comprehensive. And there is also an SOS emergency call function, which feels that the safety factor is greatly improved. It is also very convenient to use, and it allows me to know my health status very well. This watch is really a good helper for health management, highly recommended!

I was pleasantly surprised at how good this was for the money. It counts steps well, offers bpm and blood oxygen which seem to be in the right level and once connected to your phone you get notifications on the screen and I have even received a phone call. The sound was OK but it did the job when my phone was out of reach. The strap is very comfortable and seems pretty sturdy and the battery life is about five days if in full use. Charging is easy and pretty quick.

I am starting with the band on this watch. It is silicone and very soft yet durable. Now the watch itself is very good. It is easier to program with the app. I can read texts, emails, and answer the phone from this watch. However those are not really what I wanted this watch for. It also does oxygen levels,One-click physical examination, five internal organs test, uric acid test, blood lipid test, 24-hour continuous dynamic heart rate monitoring, blood pressure monitoring, sleep monitoring. This also has different faces so I chose one I like and will change it when I want to.

It is very comfortable, it is beautiful and it has very good visibility.
