Viking really lives up to their motto of what they call the five Ss: safe, soft, strong, simple & silent. Made for children 12 months & up, all the parts are somewhat rounded & a little flexible so it would be hard to injure yourself on one. The Swedish designed Chubbies are a nice, chunky size for toddlers but they're still little enough to pop in a diaper bag to take with you. I like the simplicity of them, the bright colours & lack of branding. They're not recognizable models of vehicle, mostly just classic-inspired vehicle shapes like a pick-up truck, a sedan, a convertible, airplanes & work vehicles like ambulances, fire trucks & what Sprout calls 'dumpa tucks'. Some have moving parts other than the wheels: the fire truck ladder can be extended upward or folded down; the plane propeller spins; the dump truck can tip its bed up. An added design feature--they make very little noise when rolled along any surface.
Though I like to avoid plastic toys whenever possible, the fact that the Viking Chubbies are so durable & easy to clean--you can put them in the dishwasher!--is a big bonus. Their durability makes them more eco-friendly--you won't be tossing them in a landfill because they break quickly. Viking also claims they are recyclable, though the toys aren't marked to indicate which type of plastic they're made of--I doubt they could go in curbside recycling.
Possibly the best thing about these little cars is their price: they're around $2-3 each, so pretty much anybody can afford them. Compared to similar priced toys, these seem like much better quality.
*I was not compensated in any way by Viking Toys--we just like these little cars!
