## Customer Reviews

### ⭐⭐⭐ マイクロソフトでビデオ再生できない。
*by  on Reviewed in Japan November 27, 2024*

ビデオ再生するには別途年会費支払ってとの事。カメラ、再生するには別途費用がかかると販売広告記載してほしかった。

### ⭐⭐⭐⭐ 向上してます。
*by  on Reviewed in Japan December 8, 2024*

ＳＪＣＡＭは、3台目です。小さいのと、画質も満足してます。SJ5000より、少し小さいようで、水中ハウジングなしの三脚座のみのカバー？（今回のには付属してない）が少しゆるくなりました。バッテリーや、付属品も前のが、使えるのでいいです。ただ、前回のSJ5000、その前のsj4000だったか、SJ3700は、2～3年ほどで、レンズが曇ったり、しろやけしたりで、ダメになりました。値段が安いので、また購入しましたが、手振れとかいろいろ向上してます。

### ⭐⭐ 価格相応？
*by  on Reviewed in Japan June 30, 2025*

自転車のドラレコ替わりとしてループ録画で使っているが撮れていたり撮れなかったり安定しません、この価格帯のものに期待してはいけないのか。。。
