What owners single out
In their words
“WIN10搭載のRZ4のサポート終了したのと、筐体が痛んできたので買い換えを決意。2年ほど前から軽い(800g以下)のを探していたところ、これを発見。大学生協の推奨スペック(Corei-5 12世代、メモリ16G)の条件を満たしていたので購入しました。軽さにおいては問題なく、動作上も問題なしです。オフィスはMicrosoft製品ではないですが、365を契約しているのでこれも問題なし。 まだぶつけたりしていないので耐久性は評価不能ゆえ「普通」、音質もyoutubeのセリフが聞ければ問題にしていないので「普通」としましたよ。”

“急にパソコンが必要になってPCnextさんを利用させていただきました。簡単な質問に答えて出てきたおすすめパソコンを目安に、同系シリーズを比較して決めましたがとても満足しています! 動作も快適で、本体にもほとんど傷もなく、中古でこれはかなりお買い得だと思いました。 注文して2日後に届いてくれて、本当に急に必要だったので、初期設定なども特に必要なくすぐに使えたのもありがたかったです。 中古パソコンを買うのは初めてでしたが、もっと早く利用したらよかったと思いました。ありがとうございました。”
