## Customer Reviews

### ⭐⭐⭐⭐⭐ 駅のアナウンスを録音できるのがいい！
*by S***H on July 21, 2025*

３歳のこどもが自分の名前を付けた駅名を「〇〇ステーショーン！」と録音した駅アナウンスを聞いてしまうとなかなかかわいくて、ちょっとお高かったことも忘れてよい買い物をしたと思ってしまいました。いいですよ、これ。

### ⭐⭐⭐⭐⭐ ブリオのスマート踏切
*by ち***ょ on February 7, 2025*

別売りのスマートテックの電車と組み合わせると、踏切の手前で止まったり、進んだりと幼児がとても楽しんでいます。スマートテックの電車には、エネループなどの充電池を使用すると上手く反応しないです。電車は走るが無線ははんのうしなくなるので、もしかしてブリオ製品の欠陥なんじゃないのか？と思いましたが、違いました。たぶんニッケル水素電池は、アルカリ電池と比較して電圧が低くなるからだと思います。電車にはアルカリ電池を使用するのがポイントです。ブリオはよく設計されたおもちゃだと感心します。

### ⭐⭐⭐⭐⭐ 雰囲気が良いです
*by A***ー on June 29, 2019*

発送が早かったです。デザインも気に入っているし、電車の音もリアルで良かったです。
