Is this LEGO set a good investment?
“While Accessory Pack has been slightly underperforming yearly growth when compared to other sets in HERO Factory, at an average annual growth rate of around 7%, this set is still a decent investment for most LEGO collector portfolios.”

“The Accessory Pack is a very nice parts pack (even if you put the brain slug aside). If you happen to know a LEGO store near you (or decide to order Hero Factory sets online), I can only recommend you to get this pack, since it comes with a small yet versatile number of... More parts.”
