Review: 非常にいい。 音もいい 打鍵感もいい デザインもいい コスパもいい 機能性もいい ライティングもいい 素晴らしい かっこいい いい
Review: 前々から尖ったデザインをしたキーボードとして認識しており、元々使っていたキーボードのいくつかのキーが接触不良になってしまったので満を持してこちらを購入。 最初はキーの側面に文字が印字されているデザインに上手く使えるか若干の不安がありましたが、結果として全然問題ありませんでした。 コトコト系の音もタイピングしていて心地よい音だし、ライティングもgravastarの個性的なデザインが映えて更にかっこよくなるし、使っていてかなり楽しい気持ちになる良いキーボードだと思います。 とにかく本当にカッコいい！

とにかく打鍵感、打鍵音今までで1番いいです！コトコト系のキーボードを探してる方はこれを買えば間違いないです！ 専用のRGBをいじれるソフトもありますし、2.4接続、Bluetooth、有線3つに対応してますし、めっちゃくちゃ便利です！ またK1のほうはアルミボディーで重みもあってゲームをする時にズレずらいとこもおすすめです！
