Review: 値段の割に良い性能 - このサイズで、見やすくとても良いと思います。 値段も40㍉でこの値段なら良いのではないでしょうか、 レンズキャップがそれぞれ4つありますが、外した時に無くしそうなのでそこだけ気をつけないといけないかと思いました
Review: よく見える - 価格は安いですが、裸眼で見えない星がたくさんみえました。

### ⭐⭐⭐⭐⭐ 値段の割に良い性能
*by R***Y on November 15, 2025*

このサイズで、見やすくとても良いと思います。 値段も40㍉でこの値段なら良いのではないでしょうか、 レンズキャップがそれぞれ4つありますが、外した時に無くしそうなのでそこだけ気をつけないといけないかと思いました

### ⭐⭐⭐⭐⭐ よく見える
*by A***ー on November 27, 2025*

価格は安いですが、裸眼で見えない星がたくさんみえました。

### ⭐⭐⭐ 重い
*by 一***茶 on July 3, 2025*

性能はいいと思いますが、散歩で持っていくには、重くて手や首が疲れます。買うなら重量も重視した方がいいです。
