Marble Run - Battery Powered

 I had an eye on these for a while and Aliexpress had one on offer really cheap so I grabbed it.

The marbles sometimes get stuck in the wheel, when too many come at once, but otherwise it's mesmerising to watch.

Some larger pieces were a but warped. Also I noticed there were quite a few duplicate pieces in the set, so if you break one there's a replacement, especially the spiral, which I did break and noticed after there was a second, but I had already glued the first one. So that's really good.
