My new gadget

My wife found the fitness tracker Mi Band 4 by Xiaomi in the street last week. She asked me could we find the tracker's owner, but after some searching on the Internet I got we could't do it. We gifted the same tracker our son his last birthday and he said it was a useful thing, and I decided to try using it for me. At the first, I chose another display skin for the tracker. I spent on choosing about three hours because it was too hard to choose the single one. There were tons of them.
I wear it a few days already. I can say tracker is an useful gadget. I can see the distance I go every day. And each message my phone generates is doubled in the tracker. It is very useful when the phone is far from me. I wear it around the clock because the tracker analyses my sleeping as well. I want to test it in the swimming pool because it has a feature for tracking swimming training.
