These are way bigger than what I thought they were going to be and they are fantastic they're super easy to use and the balloons are really nice with the cars. My nephew was 2 1/2 and he was his name and he absolutely loves to hook it up pump the balloon up with air and then push the button and watch them go. They work really well for outdoors and indoors. They came super fast I had no issues with the seller. I bought a couple Saturdays and they have been a big hit with all of him and his friends playing with them outside. They're super nice to have it as an entertainment for a kid to give them something to do outside. They are really well-built and came with extra balloons and extra necessities just in case you missed parts are broken and it's really easy to use which I'm really pleased with.
