My Son is fairly fickle when it comes to toys. Although he likes most Hotwheels/Matchbox playsets for a short period of time, they quickly go to the corner. This has been the exception. There is something inherently fun (for him) in acting like he is painting a car with water.

Overall, pretty durable, can be used inside with a towel underneath it. Cars can be bought almost anywhere.

My 3-year-old son loves his color shifters cars, so we bought him this to go with the cars (before he was just using tupperware containers with hot/cold water). Honestly, while it is fun for him and he likes it, I was disappointed. It is a lot smaller/flimsier than I expected it to be and think that for the price we paid, we should have just bought a squirt bottle and used some car tracks and tupperware that we already had.

Definitely search for this at a retail store you’ll pay between $[...]. It took me a couple weeks to locate one, however. The unit is very sturdy and not that messy, though it is clearly only an outdoor toy. Don’t kid yourself that it can be managed inside! The spray bottle only rests in a depression, it can be picked up and is very easy to refill. It has a rounded shape which makes it very easy to turn and tilt in the depression in order to direct your spray from any angle. There are hot and cold water reservoirs with lids which hold approximately 5-6 oz. each. A removable small basin catches the spray water drips beneath the cars. When you have changed your car color, a lever may be pulled which raises the car and makes it slide down the curvy drive. A spring arm thrusts the car at the end of the ramp away from the base unit. The swing arm must be manually reset for each car-no biggie. My boys love the play value of this unit and it adds tremendously to the enjoyment of the color changing cars. The cars change color very quickly and easily. We have found it works best with just warm tap water, but then ice water. Cars can be dipped in the water reservoirs to make them half and half, or dipped in the water whose temperature will quickly reset the color to be changed again. Two thumbs WAY up!!! The color changing cars can also be found in retail stores for about $[...]-I got most of mine at Walmart (as a two pack; 1 color changer, 1 regular hot wheels car) for $[...]. I haven’t seen the two-packs offered anywhere but Walmart.
