Great for toddlers, solid value
I bought this Mega Bloks First Builders 80-piece Big Building Bag for my 2-year-old (just starting with building toys), and here’s how it’s worked out: What we like: The blocks are just the right size for little hands — easy to pick up, stack, and knock down without being frustrating. The colours are bright, the shapes varied, and the kids (both my 2-year-old and our visiting 4-year-old cousin) both had fun making towers, houses and “garages” for toy cars. Cleanup is easier than expected — the sets come in a bag and it’s simple to dump them in at the end of play. For the price I paid, the value seems really good. What could be better: The blocks don’t interlock super tightly — if your toddler builds a tall tower, it sometimes collapses with the slightest knock. So if you were expecting super stable structures, you may be a bit disappointed. Some pieces are large and basic (which is good for young toddlers), but may be less engaging for older kids who want more variety or smaller detail. Final verdict: If you’re looking for a toy for a toddler (ages ~1-3) that helps with creative play, fine motor skills, and stacking/knocking down fun, this set is a very good pick. It won’t replace more advanced building toy sets when your child gets older, but for right now, it fits the bill. I’m giving it 4 out of 5 stars because it hits all the major marks for ease of use & fun, with just minor caveats around stability and “growing with the child” potential.

Great Item!
My son absolutely loves these mega blocks. They help with fine motor skills, problem solving and are also age appropriate. He is 18 months. The bright colors are helpful, and I love that there is a carrying case. My son can pick up the case annd bring it ancross the room when he wants to play. They are holding together so far and definitely worth the price.

⭐️⭐️⭐️⭐️⭐️ Perfect for Toddlers and Safe for My Classroom!
⭐️⭐️⭐️⭐️⭐️ Perfect for Toddlers and Safe for My Classroom! As an Early Childhood Special Education Teacher, I absolutely love the MEGA BLOKS First Builders Toddler Blocks! The larger size is perfect because I don’t have to worry about choking hazards. Many of my young students with Autism still put things in their mouths, but these blocks are completely safe and have been a wonderful addition to my block center. They’re durable, colorful, and great for building fine motor skills. Highly recommend for any classroom or home with little ones!

Highly Recommend! The perfect block set
My toddler is obsessed with these, 3 months into having them and they are used daily! Perfect size for toddlers and younger children to build with, perfect for sharing and independent play. in addition there is no choking hazard with these which make them all the better. There are a lot of pieces which could get lost, but with a close eye they’re pretty easy to keep together.

Fun and easy-to-use building blocks, but pieces may loosen over time
These building blocks are very easy to use, even for younger children. My 1.5-year-old enjoys playing with them, and my 3-year-old also loves building and creating. They are suitable for a wide range of ages and provide a fun, engaging activity for kids. Assembly is simple, and the blocks fit together well initially. However, after some use, the pieces can become a bit loose and don’t stay connected, which is why I didn’t give five stars. Overall, this is a good-quality product that encourages creativity and fine motor skills. It’s a great addition to any child’s toy collection.

Great Set for Toddlers and Skill Building
I bought this set for my one-year-old son to play and help build his skills. It comes with 80 pieces (I haven’t counted them yet, but it looks full). I really like that it includes a small storage bag so the pieces can always be kept secure. The price is great for the amount of blocks you get, and they’re very cute. The blocks can be used to build lots of different things, and the examples on the bag are a nice touch. Great value and fun toy for toddlers.

These Mega Bloks are an absolute win in our house. They’re sturdy, bright, and the perfect size for little hands—easy to snap together and pull apart without frustration. My kid can build towers, animals, and wild imaginary creations for ages, and they actually stay together instead of collapsing immediately. I also love that they’re durable and easy to clean (because… life). They’ve survived being stepped on, tossed in bins, and daily play with zero issues. Great for creativity, fine motor skills, and quiet playtime. Would happily buy again for my kids or to gift to others.

Unsere Tochter hat die Bausteine kurz nach ihrem ersten Geburtstag bekommen und spielt seitdem fast täglich damit. Die Teile sind schön groß, sodass sie gut gegriffen und zusammengedrückt werden können – perfekt für kleine Hände. Es macht ihr sichtlich Spaß, immer neue Türme zu bauen (und natürlich sofort wieder umzustoßen 😄). Was mir besonders gefällt: Die Farben sind freundlich, aber nicht zu grell. Die Steine lassen sich leicht zusammenstecken, sitzen aber trotzdem stabil genug, damit nicht alles sofort auseinanderfällt. Außerdem sind sie sehr robust – schon einige Male durchs Wohnzimmer geflogen und immer noch wie neu. Insgesamt ein Spielzeug, das die Motorik fördert, lange interessant bleibt und auch noch Ordnung hält – dank des praktischen Beutels.

Piezas grandes y encajan super bien, nada de quedarse sueltos como otros. Mi hijo hace juguetes y se pone a jugar sin que se le desprendan las piezas.
