Plain and simple – a wired PS2 optical mouse offering great value for money and ease of use. It also has a small extra button which performs a double-click increasing your productivity and reducing fatigue. Sometimes the simplest things are the best – the OP-620D is essentially a basic PS2 mouse which offers good quality at a very attractive price. It has the usual left and right-click buttons plus middle scroll wheel but in addition it offers a small ‘2X’ button which performs a double-click when you single-click it. This reduces fatigue noise and microswitch wear and tear whilst at the same time increasing productivity.
