This has been a super fun toy!
As a water bottle, this does leak. However, if you do not fill it up all the way, it only leaks if you hold it upside down.
As a toy, my son loves to put his other cars into the area where the water bottle is suppose to be and walk around the house using the bus to carry his toys!
It has been a lot of fun to watch him play with it and he has a lot of fun!
