Being an adult, I can only speak to the adult karts The karts are well maintained, fast and easy to drive. We went on a Friday night and there were maybe 7 people on the track which provided a good experience. 30 minutes cost 50 dollars which isn’t particularly cheap, but they do keep lap times and give you a print out after each 15 minute heat. I wouldn’t personally do more than 30 minutes but on Monday and Tuesday they have a special all you can drive for 70 something dollars, but it would probably get tiring. Helmets were reasonably clean and they had a stack of clean balaclavas you wear under the helmet.
