Discovery Toys – Crazy Climb Track | Car Track Set with LED Light-Up Race Car | Interchangeable Car Shells | Multicolor Flexible Changeable Tack | Custom Racetrack Toy | 5+ yrs

My grandson likes to grab the track and hold it above his head to watch the car climb straight up! Doing this makes the car climb about 4 to 4 1/2 feet straight up and it would apparently just keep going... until the batteries slow down after a few awhile. Battery life does seem good considering what he is putting the car through. And durable! The track has a gate piece for the car to enter and lock on the track but this is also the place where the car can and will come off the track as it comes around. Try explaining to your 5 y.o. that part needs to stay on the ground so the car can drive through it smoothly... no, part of the fun is having the car come to that section and go flying. Everything continues to work, I'm impressed.The only difficulty I had was clicking the pieces of the track together. It takes quite a good grip and some force to click them together. Of course, this is so the track is hard to pull apart and it needs it. It gets dragged around by the track to lay across chairs, pillows, tables, etc. while the car is still trying to go around. It was definitely a success on Christmas this year.Do make sure to have a little screwdriver and batteries handy to get started.
