This is a fun kit to build.  All the schematics and code are downloadable so it's great for learning and hacking.  The assembly instructions, which must be downloaded from the Adeept site, are quite good with only a couple of minor glitches.  The kit goes together well and the Arduino Uno and Nano come pre-programmed with software.  The components are good quality and a generous amount of spare parts are included (extra screws, nuts, etc).  The finished result is pretty wobbly simply because acrylic isn't very rigid and it's made of acrylic plate.
