Hi guys. You know, it's even difficult for me to answer this question. I have quite a few of my favorite Smart Devices and most of them I bought from
4Pro. For example, I just love the smartwatches I bought there. My watch phones allow you to quickly work with a calculator, alarm clock, stopwatch, timer, even watch a video. You can also activate "reminders" for important events. A variety of applications installed on the smartwatch will help to expand the functionality.
