Quality: Wooden case is very sturdy. Although many complain on the quality of buttons and joysticks used. Used bad clones of Happ Parts.
Reliability: No reports I seen for the PCB, main complain I saw was the low quality for the Joystick and buttons. Terrible Adapter system. Skip the adapters.
Ease of Mod: Difficulty 2 on non-track ball models. No data for the track ball model X-arcade stick.

Note: Don't bet too much on X-arcade's brand of adapters. Check out the Converter Compatibility thread
Note 2 : X-arcade has a Crappy layout with the 2 extra lower end buttons.
