"I'll be honest- as cool as this looked, I never would have spent the amount that it cost. Especially with such few pieces go put together... but I this one got added to our collection as a birthday present from my fiance and daughter. I ended up quite surprised of how long it took me to put together a mere 321 piece set, even though I was also watching tv. It took me longer to build the 1k+ bb8 that we got a while back! It was confusing to figure out where to get the app to control it, and it can be finicky when it needs to reconnect to a device. However, it is Very fun to drive around, and surprisingly sturdy! (We may or may not have Batman drive through the LEGO ruble of a crumbled Gotham City....) I also really enjoy the two different app interfaces to operate it! Different sounds, functions, and different styles of control. Pretty dang cool. I am very happy to have it added to my/our collection, and glad that the entire family can enjoy it for hours of fun!"
