Product description

1 pair of USB keyboard and USB mouse can be used to switch between 3 computers. The hot-key input from the keyboard can be switched between ports. Since it emulates a keyboard port, you can operate the keyboard immediately after switching. You can start 3 connected computers at the same time. Can be fully booted without switching between ports during a restart (reboot). The USB port for the mouse has a pass-through structure, so you can also use the tilt wheel function and multi-function mouse. No software installation is required. Just connect and switch to use. ● No need for an AC adapter as it supplies power and works from the USB port of the computer. Equipped with a magnet on the bottom, it can be fixed to the steel surface. Note: This product is not guaranteed to work with all computers, keyboards, and mouses. Specific buttons that require driver installation in keyboard or mouse may not work through this switcher. Resume and suspend functions are not supported by the one-touch button.

    Full content visible, double tap to read brief content.

    みなさんの評価が低いのをわかったうえで、自分は大丈夫という謎の自信から購入してみました。

    まずは良い点

    ・PC４台が多い中、希少の3台

    ・サンワサプライという名の知れたメーカー製

    ・本体がマグネット固定

    残念な点

    ・USB2.0接続　エレコムは3.0

    致命的に残念な点

    ・切り替えの10回に1回、マウスが切断される。

    　一度、切断されるとケーブルを抜き差しするまで復旧できず。

    　メーカーに相談するも、不良品ではなく仕様なので解決方法は無いとのこと。

    　そう言っておきながら、接続しているPCの情報や購入した店舗を教えて欲しいと、保証対象外の理由を探すのに必死になる姿勢はメーカーとして疑問です。

    マウスの抜き差しは面倒ですが、他に代わりが無いので、1年後に壊れたら同じものを買うことになるでしょう。

    個別にキーボードとマウスを用意すると場所はとるし、使い勝手も良くないが、この商品でそういう不満が解決で来るので良い。ただ、どういうわけかよく分からないが何かの拍子にビデオ信号が出ていないと、かってに生きている方のポートに切り替わってしまう場合があり（そうでないこともある）ちょっと不便。

    私的には、切り替えたらずっとそのままで居てくれた方が何かとありがたい。（例えば、PCを再起動して起動のプロセスをチェックしているときなどに切り替わってしまうと不都合。）
