I own this exact board. I like the space-saving layout a lot, but I do not care for the MX blacks. This is mainly because I do a fair share of typing in the sense of writing and coding, as opposed to keyboard shortcut kind of stuff. I prefer tactile/clicky keys with a lighter touch for marathon typing sessions, as I'm less prone to bottom out. Layout-wise, I'm assuming you're looking at an 1800 because you want to save space without sacrificing the numpad. This is a great board for that, but the 1U numpad zero takes a little getting used to.
Cherry Corp. boards are also not the most solid boards out there. This one in particular has PCB-only mounted switches (no plate), and the case simply clips together (no screws). It's not that it's cheaply made, it's just not as rock-solid as a Filco or a Ducky.
Lastly, the keycaps. The stock caps are POM, which are slipperier (is that a word?) than ABS or PBT. They are also lasered/infilled which means the legends are a little bumpy. These are minor issues that just take some getting used to. And if you would ever consider replacement keycaps, the 1800 layout does limit your options. A few kits offer 1800 support, such as GMK Hyperfuse. But Hyperfuse does not provide the correct bottom row for a winkey 1800, only winkeyless. Keycap support is likely to improve with upcoming group buys, since the TX1800 buy will place a lot more 1800-layout boards in people's hands. But I don't think the TX1800 has winkeys so I wouldn't expect that to change. Anyway, just don't expect to be able to use most keycap sets with this layout. All the correctly-labeled keys are there, but they are in the wrong profile. Trust me, it's awkward--I've tried it.
Because this board is PCB-only (no plate), I'm thinking about modding the PCB by drilling holes and re-wiring some of the runs to make this into a winkeyless layout. That way I can use my GMK Hyperfuse set when it arrives. I may also replace the MX blacks with some type of linear or clicky MX switch. I'm not sure if you're into that kind of modding, but just know that it's an option.
Hope this helps!
EDIT: It's worth noting that I also have a Dolch PAC keyboard which uses the same 1800 layout but has MX blues and ABS doubleshot keycaps. It's also got a screwed-together case, but still no plate. The Dolch board is definitely more solid and enjoyable to type on (for me) than the new 1800. Hopefully with some replacement switches and keycaps, this new one will get a lot more use.
