Review on LEGO DUPLO Cargo Train 10875 - Battery-Powered Building Blocks Set, Top Engineering and STEM Toy for Toddlers (105 Pieces) by Devin Jenkins

Possibly the most amazing toddler toy I've ever seen. My son just turned three and loves trains very much. He also loves building things, loves messing around with our remote control and loves playing games on my phone. This toy gives him the ability to do all those things. The fact that it's compatible with other DUPLO trains means we can create a variety of track designs. It also has "Action Blocks" that control the train's functions, and the train group can also interact with the app. Seriously, this is nothing short of amazing. Our seven year old is also fascinated by it and they can do it together for hours. It's not easy to entertain a 3-year-old and a 7-year-old with the same toy. This is a toy with which he can play and enjoy for a long time.
