Review on Enhance Your Fitness with the Smart Jet Sport Bracelet FT-4BP1 in Black by Minoru Yamaguti ᠌

In general, if you do not count on an accurate medical device, then a good health toy for the money. Pros below: Quite accurately measures steps (compared with competitors). It measures the onset of sleep very accurately. You can measure the pressure if something is bad. Several of these devices were compared with the readings of a pressure measuring instrument. They do, but within reason. For example, at a pressure of 130/80, three different devices read 121/72 - 128/78. Those. if something is wrong with the pressure, it will still be possible to see and already measure accurately. The error, in principle, is the same all the time, so it's easy to remember how much it is twisting. Connects well with smartphone. You can measure the pulse at a specified frequency. It charges fairly quickly (20-30 minutes for a full charge). Charging lasts for 3-8 days depending on how it is used. If you measure the pulse constantly, it discharges faster. Some cons: In a strange way, it can determine the end of sleep. That is, if you sleep like a log, then the dream calculates correctly. But sometimes, for some reason, if you wake up in the morning and think something to yourself, and then fall asleep again, then this, according to the device, may be the end of your sleep. The strap, for unknown reasons, can sometimes unfasten, touching clothes, and most importantly, fastenings easily fly off. And there are no spare straps for sale anywhere. In this case, the device can be thrown into the trash. For some reason, my device stubbornly does not set the age, which, in fact, does not affect the speed. And you have to get used to the fact that the steps are not measured in real time, but mostly in small blocks. For example, if you have passed 30 steps, the readings will be ated immediately for 30 steps.
