  • Too small for littles
Color: Blue
The only reason I gave it a 4-star as opposed to a 5-star: The size of these blocks is far too small for a toddler / 3-year old. Usually, they're gifted larger blocks so there is 0 risk of them having any choking incidents. They're good for a 4 or 5 year old, though. Good quantity, and the box isn't so terribly large, so they're easy to store back. ... show more

  • Gives you a lots of options.
Color: Blue
I've ordered it for my son, he is 2.5 yo and he likes it a lot. The sizes of the blocks are definitely litle bit smaller then expected but I guess it's kina my fault that I didn't check description pretty well. What I like about it, that amount of the blocks are huge and you can do different structures with it , definable givea you a lot of room to do fun stuff. Quality is ok as well especially when you consider the price. ... show more

  • Train blocks for toddler
Color: Blue
My two year old daughter really likes these blocks. They’re lightweight and easy to connect. Not super sturdy, but do the job. This set is really for making train cars to connect to the locomotive piece. There’s not a lot of variety in pieces, so that’s one thing I feel could be improved. Most pieces are typical rectangle or square bits. ... show more

  • Great building toy but a weird size
Color: Blue
Great building toy a bit bigger than legos but smaller than big size legos. Hard to explain. I thought they were bigger but they do work well and my son likes them

  • Many pieces are quite small so recommend for older kids.
Color: Blue
These are wonderful and will be a lot of fun for when my toddler is older. I like that they are colorful, as well as varied sizes and shapes which allows for different creations. BUT many pieces are very small so I wouldn’t recommend unless at least 3 years old, maybe older depending on if child is still putting stuff in their mouth. ... show more

  • Great quality blocks perfect for toddlers.
Color: Blue
I ordered these for my two year old son. His hand eye coordination is improving and these blocks are easy enough to put them together that he can do it. The set has a decent amount of blocks. There are more blocks than my toddler needs to build several different types of objects. The blocks are very well made. They attach together and stay connected. However, they aren’t so secure that my toddler can’t pull them apart. There are no rough or sharp edges. The colors are also vibrant and well made. There are no light spots or blemishes in the colors. Very nice quality and I would definitely recommend this block set. ... show more

  • Blocks
Color: Blue
This is definitely for the correct age of 3 year old. These are smaller than expected but still a decent set of Legos. It's a good amount of them in the box. More than enough to make a lot of configurations.
