Ordered to replace an old worn-out Logitech keyboard/mouse (in the Black Friday sales this one was slightly cheaper...)
Keyboard seems generally OK; quiet in operation, though very occasionally seems to get "stuck" (a keystroke seemingly isn't registered - press the next key and the "stuck" keystroke and the new one both appear...
The red LED lights to show Num Lock and Caps Lock aren't very bright; they do go out after a few seconds to save battery power. The keyboard has a tiny on/off switch on the right-hans end that seems to have been added as an afterthought.
Ergonomically, the mouse is fine, comfortable in either hand with a reasonable feel to the buttons and the wheel. But the mouse does perform very well:
(a) Movement can be erratic, and the mouse pointer will frequently jump to a completely different place on the PC screen. This may be dependent on the kind of surface it's being used on (its optical sensor may not like my old wooden desk) - however the previous mouse had no such issues!
(b) The "inactivity timeout" (where the mouse enters a low-power mode and eventually switches off to save power) is far too short:
i. After 1 minute the mouse enters a low-power state where the red LED alongside the optical sensor flashes at a slower rate to save power. Not a big issue as it only causes a small delay (less than a second) before the mouse starts responding again if it is moved.
ii. After 10 minutes the mouse switches off completely and requires clicking of a button or the wheel to wake it up (just rolling the wheel or moving the mouse won't wake it up)
The mouse's irritatingly-short "inactivity timeout" will mean that I won't be buying another one of these...
