    カスタマーの方の対応◎

    初めてのプロジェクターで不安でしたが、接続も簡単でした。モーター音も気にならず、映りも綺麗です。角度を変える時に力を使いますが、問題ないです。またスマホからの動画を見る際に専用ケーブルが必要とのことでカスタマーの方が丁寧に対応してくれました、ありがとうございます。

    画質がいい

    本体はとても軽くて場所を取らないのに、映し出される映像は1080Pでくっきり綺麗です。50%ズーム機能もあるので、部屋の広さに合わせて画面サイズを調整しやすいのも便利です。

    初心者向けプロジェクター

    安価でHDMI接続で1920×1080入力に対応しています。ただし用途はかなり限定される印象です。■良い点・価格が安く、気軽にプロジェクター体験ができる・HDMI接続やスマホ接続、USB再生など最低限の機能はある・動画鑑賞用途ならそこそこ使える（暗室前提）■気になる点・ファン音がやや大きい（この価格帯では仕方ないかも）・スタンドが不安定（三脚固定用等のネジ穴等もなし）・明るい部屋ではほぼ見えない（暗室必須）※ただし30インチ程度くらいなら明るくても少しは見えます・入力は1920×1080に対応しているが、実際の表示は1920×1080らしい精細さは感じられず、文字の潰れやぼやけが目立ちました・文字が潰れるためPC作業には不向き・操作がリモコン中心で本体操作性は低い・機能は最低限で、基本は外部機器接続前提・シアタールームのような、大画面視聴は正直キツイ（暗い、画質が悪いなどの理由で）■総評価格を考えれば割り切りは必要ですが、用途が合えばコスパは悪くないです。ただし「日中使用や、多少明るい環境」「PC作業」「1920×1080の高精細映像」を期待すると厳しいです。あくまで暗い部屋での動画鑑賞向けのエントリーモデルという印象です。■追記しばらく使用してみての追記です・画質がやはり期待よりかなり低く、高画質なFHD動画を表示させても昔の低解像度動画のように感じる画質だったため、満足できず、

    コスパ良し？

    画質も悪くなくプロジェクターとしては安価なのでコスパは良さそうですが、サブスクなどはデフォルトで使用出来ないためFire Stickなどが必要となる。そう考えると初めからサブスクが使用出来るタイプのプロジェクターを買った方が良いかもしれない。映像を映すだけであれば何も問題はない。縦の補正は出来るが横の補正は出来ないため、正面に設置する必要がある。音声はあまり良くない。音を小さくすると音飛びしたり、まともに聞こえない。小さい音にしなければ良いが、音を大きくしても稼働音が気になるくらいに聞こえてくる。
