I received mine a short time ago.
I had some concerns. There was a noise when I handled the supergun, as if a part was broken inside. I opened it and found a small broken plastic wedge.
Ok, it's probably Fedex...
No manual, we quickly understand but a manual would have been nice to clarify the operation of some settings. (although I read the info in this thread)
And then I had a problem with the kick harness and I realized that the connector on my "JAMMA extension - Japan HRS" was soldered upside down:
In short, nothing serious but a little disappointed for a luxury product.
The rest looks good although I think some things can still be improved.
: More serious, after only a few days of use, the power button remains stuck on ON... Impossible to turn off the supergun without disconnecting the power supply.
EDIT 2: The +5 voltmeter is starting to have problems....
