Quoted from DrJoe:
They are using cheap silicone for the flippers and rings. Go with polyurethane Super-Bands.
Anyone who orders a 9500-20000 toy like this should just go ahead and place the order for premium rubber so you have it on hand when you open the box.
Same thing as how most people go buy a car and immediately buy molded floormats from WeatherTech...that business is booming...Could car manufacturers provide that as an option or better yet, included for free? sure...but why would they? IF you can afford a JJP GNR, you can afford a $30 rubber kit.
I am all for bitching about the pooling, chipping, crappy decal installation, slow production but the rubber quality - while not great - that's a simple expected maintenance item and the cheapest one possible.
