"This set is mostly brilliant. We love how all the smaller vehicles fit within the whole, but the way the roof attaches to the bat base is not strong enough. We have A LOT of Lego and I’ve never known a moving part to attach in such a fragile way. I’ve come to expect much higher standards so it’s disappointing and frustrating for both child and parent to have to keep repairing it. Are there any ways it could be made stronger?"
