These Pull-Back Marble Racers are a prime example of how “good things come in small packages.” Packed inside this small package is a fun, durable and very entertaining toy car. The little race car is made of sturdy plastic which is great because it can crash into walls and fly off tables without breaking apart. We watched parents cringe as their kids sent these cars careening into every possible obstacle and then breathe a sigh of relief when it emerged without a scratch. It features a good quality pull-back motor which is quite responsive and quite speedy. One feature that really stood out, especially considering the price point, are the toy’s wheels which are not plastic (like other cars in the category), but rubber, which allows it to grab the surface and roll smoothly. The result is a car that is really fast on hard surfaces and one that can even zip along on low-pile carpeting. This was a nonstop favorite in the testing centers and it’s appeal with young testers was undeniable.
