高齢者には使いやすい
高齢の母に買いました。 スマホと連動せずに使えるのでいいです。 ボタンを押す度に万歩計、時計、消費カロリー、距離がわかるので 高齢者には使いやすいようです。

Problemas en menos de 2 meses de uso
Se lo compré a mi hija que no tiene celular y tuvo problemas para cargarse casi desde nuevo. No lo recomiendo, no resiste uso leve.

電池持ちが・・・
品物自体には問題なく使用できていますが、腕が動くと時間等が表示され、暫くすると消えるの繰り返しなので電池の消耗が早いです。せめて1週間持つと有難いです。

Accept it with a grain of salt
The frustrating part is the programming. It is very sensitive when it comes to moving from one program to another and inserting your data. My first several attempts were a nightmare of frustration and I had to hold myself in check to prevent myself from tossing it at a wall or stomping on it. That was with the first watch. But that pattern repeated with the second watch which arrived a week later. For accuracy, here is the comparison. I am utilizing this watch primarily as a pedometer. I put both watches, same brand, both fully charged, onto the same wrist and went onto a stepper. The results were the purple said 3948 steps while the green put the steps at 3388. The difference is 560 steps. That is a lot. And I don't know which - if either - is accurate. (Steppers are notoriously inaccurate, even if they appear to work - mine doesn't - hence the wrist pedometer.) Whichever wrist you wear your watch on, that arm needs to be in swing motion for the pedometer to function. The color of the band is true to what's on-screen. I ordered the green then followed that up with the purple. In dim light the band looks more brown than purple, but in light it is definitely purple. Contrary to the initial programming, after that it's functional and easy to flip through your stats. If you're going to charge into a socket, you need the adapter but otherwise the watch charge mechanism is on the unit. There is no cord involved. That requires removing the band on that side. But the band is easy to push on and pull off. Not fancy but a sleek design that also has a variety of band colors available. Lightweight. Not chunky. No app or cell connection. Not SMART. It's an independent unit so you access your results immediately. UPDATE: Still have the green one but the purple strap one needed the battery charged as I was using that more often. The battery was half empty. I used the same adapter for charging as last time but went through several outlets and it did not charge. In fact, it dropped further on battery usage. This is a return item. We'll see what the lifespan of the green strap watch pedometer is.
