So far this is a good purchase. I am giving them to my granddaughtersoul for Christmas however of course I had to try them. Must draw a thick line but they do follow it.

came as described, a Christmas present so haven't tried it as of yet

I bought this for my y year old grandson and he LOVED it! My other grandson already had one, so they drew lines that would intersect and the cars would crash, which they thought was hilarious. This actually worked better than I had expected. Very fun toy.

Smaller than I expected and does not move very fast. The jury is out until Christmas on how much the grandson will like it.

I saw item on The Vortech while browzing and ordered one out of curiosity. VERY COOL! So..... I ordered several more to offer as holiday gifts.
Very nice! Thank you.
