Hot Wheels Color Shifters Trak-Tune

Kid loves them.

Perfecto mi niño de 4 años super contento

Seller was rude....I followed the instructions listed on the package to make the car change colors as it said it would change from grey to red when placed in warm water and back to grey in cold I tried everything from boiling to ice water and no change whatsoever. When I requested a return I got an incredibly rude response from the seller . Will never buy a item from this seller again. My 3 year old was very disappointed

My son was very disappointed The car does not change color whatsoever when under hot or cold water no matter what it stays the same gray color.

It is sad. Will not work no matter what we try. Son is sad. You will just ruin hopes and dreams.

Didn’t change colors. Disappointing

As advertised.
