Review on Perixx Perimice 209 Wired Mouse Resolution by Ahmed Rowe

With the advent of laser mice, optical mice with red LEDs were no longer used. Red LED mice are actually the most accurate and least technical (hence the cheapest and most reliable). I connected my new mouse and old amazing Compaq PS2 keyboard to a Monoprice Dual PS2 USB Adapter (Revain Product ID B00IACID2C) which resulted in the easiest setup I have ever used. It is highly recommended to use both a mouse and a PS2 adapter.
