The models' case: Best all-around under-$40 wireless keyboard: reliable Bluetooth, three-device switching, quiet consistent typing, compact travel-friendly build, long battery life, broad. The models' main caveat: Add an included 2.4GHz dongle. The strongest alternative is Logitech K400 Plus — The living-room/HTPC champion — full keyboard with a built-in trackpad and left-click bar means no separate mouse, 10m wireless range, and a long AA.
