## Customer Reviews

### ⭐⭐⭐⭐⭐ Sペンをよく使う人ならマストのケースかも
*by A***ー on May 22, 2025*

■良い点・Sペンがスマホ本体と一緒に持ち歩ける。しかも取り出しやすいのにしっかりホールドしてくれます。Noteとかこれ以降のS Ultraシリーズみたく本体内蔵でないSペンが、本体と一緒に持ち歩ける。持ち歩ける、すごい。・つけるとでっかいカメラの出っ張りが気にならない程度には背面がフラットに近くなる。・上記のお陰でSペンで描くのが楽になる。ケースなしだとガタつきます。・2025年5月でも手に入る。4年前のスマホのケースがまだ手に入るのは本当にありがたい。・ボタンが押しやすい。ケースを付けてるとは思えないほど軽快な押し心地です。これだけでSペンをよく使うS21 Ultraユーザーなら買わざるを得ないと思います。主観ですが。が、それでも気になる点がないわけではありません。■気になる点・重い。全面保護してくれる代償なのでヨシ。・放熱性能が犠牲になる。特に5G通信をしてると爆熱になります。・片手持ちすると痛い。充電ポート周りの穴周辺が少し尖ってるので小指で支えて持つタイプの人には刺さり（物理）ます。・ちょっと緩い。本体から脱落することはありませんが、ポケットに入れるとスマホとケースの間に気づけばホコリが入っていることもあります。・上記により掃除が（気になる人には）必須です。・やっぱ重い。・ペンを入れる向きに慣れが必要。S21 Ultra用のSペンは平たい形で、"SAMSUNG"ロゴが見えるよう入れないとうまく入りません。気になる点を無視できるほどにはSペンを持ち歩ける+描くのが楽になるメリットが大きいケースです。

### ⭐⭐⭐⭐⭐ Sペンホールドバッチリ！
*by T***A on June 24, 2025*

Sペンを装着し使用中。使い始めたばかりなのですこぶる良好。全く不満はない。心配は、Sペンを頻繁に使う為、Sペンのホールドが劣化により緩くならないかどうか。何度かSペン無くしているので、緩くなりませんように。

### ⭐⭐⭐⭐ 使いやすいです。
*by く***ま on May 14, 2023*

純正も無くなったので、これに決まり。
