They just work and seem to be robust
I have three of these that I carry in my bag snd they just work.I did have an issue with the old blue screen of death when using one which was solved by downloading and installing the latest drivers

ポート固定/FTDIチップ使用のUSBシリアル変換ケーブル
仕事でいまだにRS-232な環境があるため、ノートパソコンにUSBシリアル変換をつなげて使用してきました。この製品はFTDIのチップ(おそらくFT232R)が使用されており、さらにあらかじめシリアルナンバが書き込まれているため、違うUSBポートに差してもCOMポートが無駄に増殖することはなく同じCOMポート番号で使用できるので快適に使用できます。また、ボーレートに関しても看板に偽りなく921600bpsでも波形がなまらずきっちり出ます。仕事で安心して使える逸品です!
