#item https://www.fitbit.com/jp/charge4 I recently bought this watch. I hadn't worn any watch for very long time, but I did not want to touch smartphone so often. So I just bought this smartwatch. Of course, this is my first smartwach. I bought a week ago, and used for a week. My opinion so far is "Not so feel good". It is very obstacle, during writing, typing, wear clothes and bag. It is good that I can see the time, but it is slow to display. I was also fascinated to measure heart rate, but I can live without seeing heart rate. Anyway, this watch is not so cheap, so I will keep wearing the watch, but actually, normal watch was better.
