Just ordered it myself. Was also debating between the 10 and 11, but decided the split would be more versatile and not take up nearly as much space. Plus, two knobs!!!
They are on backorder until mid July from mechanicalkeyboards.com but it’s free shipping and you get the assembled version for the price of the barebones
That’s what the guide is for ;)
So far pretty great! Split is great, I wish there was a better way to connect the two halfs, the extra cable clutters up my desk. Solid build quality, pretty heavy. The keycaps are already getting a bit shiny after just a couple weeks of use, which is disappointing. I went with the brown switches that have a very subtle tactile bump, but are actually much quieter than the liners I had on my k4. The two knobs are great, but I only end up using the right one 90% of the time. Macro buttons are super useful, I wish 8 could find a nice relegendable keycap for them though. Overall about a 8/10.
