Have a Hobbit and Dialed In.
Hobbit has about 12000 games played on it. Issues: One broken bumper bracket; dead LCD screen twice (bad soldering); broken ledges on drop targets so they won't stay up; one bad lighting wire harness.
Dialed in has about 4000 games played. Issues: Trap door wouldn't stay up, due to screws coming loose and parts of the mech twisting around.
Nothing more than should be expected, except for the LCD screens on the Hobbit, which were horribly soldered from the factory. Hobbit is also a bit of a pain to work on just due to the amount of mechs and wiring, really. Dialed In is much nicer in that regard, and Pirates looks to be even more so.
