Everest 60 Numpad

Looks like it has great build quality, and seems very robust. However, it does not work with the Everest Core model, only works on the Everest 60. Didn't find out until I read the fine print on the packaging.

Missed keystrokes when you're typing fast like most professionals do.

The build quality is good but there is some quirk with it that causes it to miss your inputs.

If you type the same number multiple times rapidly it will miss some of them.

I am a person who needs a numpad for work. This is great, just expand your 60% keyboard and get it ready for your work.

This numpad connects to the keyboard through a USB-C port and two tiny magnets on each side of the port, nothing else. So the slight slip, accidental move or wrong handling can break the magnets and potentially the USB-C port, making the numpad useless on that side.
And do not attempt to fix it as it can make the other side stop working. I would not buy this unless they improve the design to something a lot more sturdy. Not worth the €50 price at all.
Also, the warranty does not cover this kind of damage, so only buy this if extremely necessary.
