      These are indistinguishable from name brand Lego Duplo blocks, and fit with them perfectly. I bought this set to expand our existing Lego Duplo collection, and I literally can’t tell them apart. They’re perfect! Love that we were able to get tons more pieces for a fraction of the price. One detail worth noting is that there is an instruction book with animal designs to try building, but not all of the colors to match the examples shown. For example, no gray for the elephant. Not a big deal to me, but worth noting!

      Colors were very different from the picture, a huge proportion of pieces were the super small size. Unfortunately, there were also missing pieces when I counted them. The price is good, they were compatible with my Lego Duplo sets, and I think my kid would still have fun with them. However, I will return it since I was aiming for a set with a nicer variety of shapes/sizes and the pretty colors from the Amazon pictures.

      This set is completely compatible with Lego Duplo. This is great because Duplo is very expensive and really only sells super specialised sets with a high price tag. This set allowed my son to have building blocks he can explore with and use his Duplo bits with it. The sizes are good, the colours are fun and I can look my wife in the eye after buying it!
