Review: この価格（¥2,278）でこの信頼性はとても良いと思う。 舗装路しか走っていないけど、ロックすれば絶対に落ちないし、ロック忘れても平らな道なら大丈夫そうに感じる。 段差をガンガンやってれば、いつか破断するかもしれないが。
Review: なかなか良い商品です。 ただ、スマホケースに固定部材を貼る時はちょっと難しいです。 自分はたまたまなのか上手く貼ることが出来ました。

なかなか良い商品です。 ただ、スマホケースに固定部材を貼る時はちょっと難しいです。 自分はたまたまなのか上手く貼ることが出来ました。

### ⭐⭐⭐⭐ Review
*by ビ***ブ on November 25, 2024*

2024年11月にスマホ片手運転が違反になりました。 スマホはガーミンマウントで無理やりくっつけていましたがガーミンマウントは耐久性がなく割れてしまうことが多かったです。 このマウントに変えた所安定して付くようになりました。 ただ 完璧ということはなく中途半端に入れてしまうと外れることがあります。 あと接着テープでくっつけるのでケースの材質はプラスチックである必要があります。シリコンはだめです。軟らかい素材はだめですね。 不満点はロックの機構が左下の小さいノブレバーをかけるとこです。小さすぎるのでやりにくいです。
