I was hoping to use the trucks in our sand box with threes, fours and five. However, they are not sturdy enough for the this age group. I cannot put them in the toddler sand box, because they are labeled "not suitable for children under 3". :(

The kids instantly loved playing with these in the sandbox to dig and drive. They are the perfect size for preschoolers. My only complaint is that they were a little stronger. Several of the plastic parts came apart on the diggers. Most of them I was able to fix with little frustration.

My two year old son just loves these toys. They are toys but have own mechanism just like real ones. They are very educational and also fun. My son lives with them. Best toys I've ever bought for my son.
