"I bought this set for my Nephew (aged 6) as a Christmas gift. The build is pretty straight forward enough, I gave him a hand with the engine and his dad helped with the trailers.
Pro's: The Bluetooth controller has variable set speeds and can be programmed for more than one train set.
The over all construction is nice and solid, so won't disintegrate easily if it falls off of the track.
Train carriages have nice detail and easy access roofs for play.
Cons: The 6 battery power brick makes the Engine piece top heavy, making it very easy to topple over at higher speeds.
Needs more track. The set could have been massively improved with the addition of a least 2 more straight piece's. for the price I would have liked a little more track.
Tips: Don't forget this set requires 10 AAA batteries to operate, 4 for controller, 6 for the engine.
younger builders may need help depending on build ability.
A small screw driver will be require to open the battery compartments (philips or flat head will work).
I would suggest buying extra track sets 60205 and switch tracks 60238, these additions will massively improve your base set."
