https://www.amazon.com/Magicforce-Mechanical-Numeric-Backlit-Computer/dp/B07K22N266 It’s a Magicforce brand with Cherry browns. I do not love it, sometimes it acts funny with my Lenovo docking station. I feel like you can find a better one with wireless these days if you look around on Amazon a bit.
Not really, mostly for looks. Some people like that they come apart in the middle but I haven’t found that to really help in any way. At home I use a normal very basic cable. I had some rewards points on drop that I used for a few things and that cable found itself in my cart. I probably wouldn’t spend much on a keyboard cable unless you want a specific look.
