Over the past few months I have been observing the quality of Stern builds. I have specifically been comparing the pro and premium models of the same games. My observations of the two models have led me to believe the quality of the Pro model is superior to the Premium. The three games that I have compared are AC/DC, Metallica,Ghostbusters and GOT. There are many more but these were the ones I noted. The premiums have additional items in them that often fail. There are many examples of this which I had observed. On the Metallica Prem, I have observed the snake and hammer to fail on multiple occasions. The Metallica Pro has not had these issues….grant it the pro does not have the hammer or snake jaw assembly, but thats what makes it a pro. This was just one of the many areas I am referring to. I’m interested to see if anyone else has noticed any differences in builds and feel the Pro is a better quality product.
