My 2.5 use old grandson loves his train. I bought so he could play with it at my house and it keeps him busy for hours. The tracks are interlocking, so easy to put together and it's smooth - no rough edges. The magnetic cars stay well, even as they take turns a little fast. The bridge is a great bonus! It comes with lots of accessories: signs, people, trees, etc. It's an all around great gift! Oh, and when he's finished playing, I slide it easily under the couch.

This track is great. Made well, and littles can put together themselves. Love that extention tracks can be bought. My grandson loves this. It comes with 3 magnetic trains as well. The only downside is there is a piece of track about 2 in. Long that kept getting lost and another that connects the bridge. I glued them on and no longer Problem.

Bought these for the grandkids. My husband ended up spending hours with them, building things. Every time they come to visit, they bring those out! Took them to a BD party and it sure kept the younger kids (and some adults!) busy.

Can't beat the price for these and how many you get. My daughter loves building with these and learning how to think through building simple things like houses. Great long term gift.

My great granddaughter loves the block. I have been using them to teach her the alphabets and colors. She lkie to stacking them up even though she knock them down after stacking. They are durable and I love the mesh bag for storage. I highly recommended the SainSmart Jr Wooden ABC Blocks for your little ones.
