Does the job
I use it on a Windows 10 PC. The OS recognises and installs the driver automatically.
The keys are quiet but a bit soft, not the best feeling but in use this is not a problem, unless you spam the same key quickly.
The keyboard automatically goes into sleep mode after 5 minutes, and comes out of this state as soon as you press a key. It's impossible to turn it off. I've been using it for 4 months now and I still haven't changed the battery.
The wireless range is good for normal use.
Sometimes the keyboard goes to sleep instantly or at least the numbers don't go through. I don't know if it's the lack of battery or that sometimes the wireless signal is bad but it's quite rare in my use.
I'm still satisfied, this object allows me to gain in ergonomics on the desk and to use it with the left hand when I have a lot of numbers to fill in.
It's the only wireless keypad on LDLC at the time of writing this review so I can only recommend it if you're looking to get rid of a cable.
