Review: 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.
Review: 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.

## Questions & Answers

**Q: Are they BPA free?**
A: The answer from September 18, 2018 is not painting a full picture, and is slightly uninformed.  Ploycarbonate (PC), like most any other plastic, can be colored.   Polycarbonate is able to achieve great strength and clarity, which is why it is often used in clear applications, but you'll find colored plastic parts/products made of PC.  BPA is also used in the production of most PVC products - from the looks of it, the storage bag is made of PVC, which is also likely why the product carries the Prop65 Warning (PVC is part of the prop 65 list of naughty materials).  You'll see the same Prop 65 warning on most inflatable water toys, as most are made of PVC, because of it's flexibility, durability and ability to weld using high-frequency welding machines.

**Q: Did you compare these with Legos before you purchased?  What made you decide on Mega Bloks?**
A: I have a 6 year old with Aspergers and he prefers Mega Bloks for building letters and numbers because of the unique shapes of the bricks. He will build letters and numbers for hours. We have Legos for buildings, cars, and other things.

**Q: Where are they manfactured?**
A: My set says "MADE IN CANADA" on it.

**Q: The flat wheelbase has 4 pongs per side or 5 pongs per side?**
A: 4 pongs for 4 wheels
