These little toys are so cute! My teenage son and husband started unwrapping ALL of these and started having races with them! They were like big kids! It was actually a good way for them to test them out! Some go side to side, some flip (which I think is the coolest). Then there are the ones that go straight, and the ones that start to go straight then go in circles and go straight again, a pattern if you will.
I had two, the "cockroach" and the "puppy" that really didn't want to move. After fully winding them up and letting them go to do their thing, these 2 didn't seem to want to go anywhere, unless you forced them by pushing them with your fingers.
I like the variety of characters that are available, even the Santa and Snowman that have skis in their hands! The box it comes in reminds me of a store display when it is set up properly, but we use it as a container for them! They are fun for any age, and so far, don't have any major issues or concerns! Just going to have fun with these now! Hoping they'll last for a little bit, too!!
