A4Tech OP-620D 2X-Click Wired USB Optical Mouse

The A4Tech OP-620D is a wired USB optical mouse whose distinguishing feature is a dedicated 2X-Click button: one press opens a file or a folder, so the double click that fills an ordinary working day happens with a single finger movement. Around that sits a plain, comfortable symmetric shell that works for left and right handed users alike. The optical sensor runs at 1000 to 1200 DPI, tracking smoothly and accurately for document work, browsing and file management. There are 4 buttons in total, including the 2X-Click, and the scroll wheel is a nearly frictionless, dust-resistant design that keeps turning cleanly in a dusty room rather than gritting up after a few months. The switches are rated for 5 million clicks, the USB cable measures 150cm, and the mouse works on Windows XP through to Windows 10 and 11 with no driver installation. The body is compact at roughly 119 x 63 x 36mm and about 91g with the cable. This is a long-standing favourite in the entry-level class in Bangladesh, and it holds that position by being unremarkable in the right way: it plugs in, it tracks, it lasts. Offices buying in bulk, homes replacing a dead mouse and cyber cafés running machines hard all day are the natural buyers. It comes with a 1 year brand warranty.
