Either they forgot to put the connecting pieces in the box or they are a manufacturer error and all males end pieces are missing. They are either not connected or the manufacturer forgot to pack them. Either way, they are not connected.

The items are quite sturdy and the product bag they came in is also durable. They seem to be sturdy but we have only used them a couple of times so far. They are a little fragile, but i do think it's worth the buy.

Had lots of fun playing with our grandchild. There is a little funnel that you can pour sand or water in, and the wheel below goes around. Lots of trips back to the water lol.

The bag that comes with it is great too! Plus a mesh carry case that can be worn like a backpack. Has netted part to drain out water for an easy cleanup!

They are tiny and flimsy. The only thing i like about it is the funnel that spins when sand or water is poured in it.
