I was replacing a Happy Hacking Keyboard Lite 2 (HHKB) which has served well on and off over 10 years and was looking for a similar compact layout with quality mechanical keys. After considering several options I selected this keyboard. It has quality Cherry MX 'brown' keys, a 60% layout and some layout flexibility.
What you get - a sturdy keyboard with a bit of heft despite its size - not in the least flimsy. It has a blackdark grey matt finish with white top printed keys (and additional functions printed on the front). It comes with a keypuller and a handful of extra alt-printed keys if you want to configure some key functions (more on this below). DIP switches for this purpose are on the bottom with a clear diagram showing their functions printed on a sticker on the base. There's a more expanded diagram on the box and a pamphlet included with similar diagrams, printed in Japanese and English. It comes with a lengthy USB cable (1.8m) which plugs into the rear and an adjacent full size USB 2.0 connector.
Layout - this was an important consideration for me. First, its US layout which suits me. (A GB layout is available.) It's a 60% layout with cursor keys so there are some compromises. On this keyboard (as in most other 60%s) the Escape key is on the number row at the left, in this case displacing the `~ key to the top right next to =+. Esc to the left of '1' suits me as I use emacs and expect Esc to be handy. The HHKB is similar in this regard. The cursor keys are squeezed onto the bottom right with the Delete key located below Enter. Unfortunately this forces the right Shift key to be small and this, if anything, is the most difficult thing to get used to. It is relatively easy to hit up-arrow by mistake but hopefully I'll get more precise over the coming weeks. Also notable is the small space bar flanked by Fn keys. I have not found this a problem but if you find that's the case you can use DIP options to make either or both Fn keys act like space.
I like the traditional UNIX keyboard layout and it was a consideration for me to have Ctrl to the left of A (again, so its handy for emacs). There's a DIP which allows you to swap Ctrl with CapsLock together with alternatively printed keycaps (see pic). The other change I made was swap Backspace with | so Backspace is right over Enter (pic). This gets around the rather small Backspace key which was located at the top right. If you want to have `~ at the top left where it is on a standard US layout you can swap around the Esc and `~ function on that key. I can only imagine this would suit someone who never uses Esc.
Use - it's been a pleasure to use so far. The keys feel great and the layout is close to, if not exactly, what I want. It also feels like it will last a long time - hopefully as long as the HHKB. Definitely recommended if you're looking for a 60% keyboard and are content to live with the layout compromises.
