I like them I have the tumbler,and it comes with a peace of paper says that it should not move,so I unscrewed it and the fromt wheels in side need to be cut like a circle so they work and the back wheels you can move it and here a breaking sound and then the back wheels will move, the wheels are on a sliver bar thing and they will be ok and a plastic pic which keep it from
moving will be broken,so now the tumbler will move, and the figs are nice and the dc line are good too.
