Razer Gaming Mice Technology: Precision Laser Sensor - Razer United States. I am still in love with my deep travel, mechanical, keyboard from Razer. I got one for home and the office, and the satisfying click, click, click of the keys brings me back to the early days of computing, when mechanical keyboards were ubiquitous. These days, short travel keyboards and chiclet keys are common, with manufacturers wanting to make them prettier and lighter. Well, I prefer the old keyboards, and gamers get it. Razer makes keyboards and mice for gamers, who require precise pointing, and fast typing. So, I also traded in my old wireless mice, for a couple of Razer laser pointer mice that make my document work much faster and easier. Why should gamers have all the fun? Of course, the light up keys and mouse, with the snazzy Razer logo make me look like a teenager at his computer; but, I can handle the ridicule as long as I can keep this keyboard and mouse. Mouse on.
