This is a great little kit. It does have a few “quirks” like many japanese kits – You can build it with either Wheels, or working lights (Wheels- On TB4 Really!) But I built it stock and left both the “optional” features off. Its a fun little build that is quite accurate to the original TB4 (and not the horrible movie version or the modern Weta version.) You will need to be somewhat skilled as the instructions are in Japanese so probably not good for a child to build. Oh, and it comes with a cool base to display it on. If you are a Thunderbirds fan, its cool.
