It is all metal but the baskets came a bit bent in places. With a little effort, they bent back into place, but I hope it doesn't affect their durability. The wheels have an issue: they consist of 2 wheels that are connected to each other with a metal rod. The problem is that the hole where the rod goes in is sometimes slightly larger than it should be, resulting in the wheels constantly disassembling. In the end, it's okay, especially if I can replace the wheels.
