Definite problem! Looks like the inserts become loose under the clearcoat and get worse with heat ..play ...and wear.
The problem with Stern is getting anyone to call you back(after filling out their petty website form with your phone number) to buy specific game parts or get troubleshooting help.
The Software codes update are another problem, as all the best Software programmers get hired to work for Slot Machine companies like IGT, Aristocrat, Williams etc ..
I would wait 3+ months before buying a new title, but I guess it must be an obsession to keep buying new release Stern games one title after another...even knowing they have problems? Very few, if any increase in value like all the Bally/ Williams games used to do?
