Easy to assemble, just be careful of pinching the wires. It almost feels like the case needs to be a millimeter bigger in every direction. The daughter board is snug fit, the wires need to be carefully placed. However, once you're done with that, your Cheap Yellow Display is ready for action.
So far so good. I have a certain fondness for hardware that eliminated the need for soldering since i am blind in one eye. .
Lookin forward to gettin other gear
The board is great. My only issues have been with the gps antenna and the case. The antenna is being detected in marauder and on bruce but cannot get a fix. It sees an antenna is connected. The other issue is the case. The top broke when I unscrewed it to put in the cyd. Luckily I have a 3d printer and was able to print another.
EDIT: After a quick tear down and a reflash of the firmware, everything is now working.
