Every model is tested over a full working week before it joins the catalogue. Wireless mice have to switch between machines without a re-pair, keyboards have to stay quiet enough for a shared room, and cables have to survive being coiled, uncoiled and dragged off a desk.

Dual-mode wireless on almost everything, so a laptop and a desktop share one mouse.  ·  Keyboards in mechanical, membrane and low-profile builds.  ·  Cables and chargers rated for daily plugging, not occasional use.
