## Customer Reviews

### ⭐⭐⭐⭐⭐ 文句ナシ
*by A***ー on April 23, 2025*

つまみがあって使いやすい。安い。色もいい。

### ⭐⭐⭐⭐⭐ 緩んだストラップをガッチリと
*by 目***！ on August 20, 2025*

ロック式のストラップピンは出っ張るのが嫌です！！これは類似商品と違い頭一つ出ています！！まさに形で出っ張っている部分があるので取りやすいです！！アーニーボールのストラップにダダリオと何の拘りもない私の感想です！！(笑)

### ⭐⭐⭐⭐⭐ 目立たない。かつ手軽に確実にストラップ抜けを防止できる。
*by パ***） on July 10, 2025*

手軽に取り付けできてしっかりロックしてくれます。また、これ自体がシンプルな黒いラバー製なので目立たないのもポイント高いです。（取り付け穴付近の素材が黒いストラップなら遠目には付けてるのがわからない程です）取り付けが簡単でこれで本当に抜けないのかと不安になりますが、実際しっかりロックしてくれて肩にかかる位置を何度も直したり動きながら弾いてもまったく落ちる気配なしです。これで4つで700円程度ならコスパ抜群。期待以上の性能・使い心地でした。
