“With the Clone Wars era and Prequel Trilogy in vogue at the moment, Clones like Captain Rex are highly sought after by LEGO Star Wars fans, many of whom grew up with the Prequel Trilogy as their Star Wars, and are now coming of age and have a bit more disposable income to... More spend on their childhood pursuits.”

“I think it’s great that LEGO now has such an important character in one of the cheapest sets in the portfolio. The Microfighters remain a reliable source for very good minifigures. Along with Boba Fett's Starship Microfighter and The Mandalorian N-1 Starfighter Microfighter,... More we get one of the best minifigures of the current Star Wars portfolio here. The issue with the Venator is annoying but not really surprising and cannot be blamed on this set.”
