Title: Save your money. Buy the non-powered version
Review: This was a Christmas present for my 2 year old boy. It has a strong motor will push and pull well, go up hills etc. However the middle set of wheels tends to bind in short curves and switches and this derails the engine (or it gets stuck). It can run unaided only on the simplest of tracks. My 3-4 year old couldn't keep his hands off it though. The motor lasted less than 3 months. Not for the child that likes to take things apart as well. I chose to return it when my son started picking the rubber grips off the wheels. I had high hopes for this product but it wasn't a good fit for my son. Better for a gentler, less inquisitive child. So consider your kids temperment and maybe save your money and buy the non-powered version.
