Good toy but overpriced
These make for a brilliant toy- educational, fun and lots of combinations to be made. I do find them a bit overpriced and they aren't the most robust, but my son looks after his well so nothing has broken as yet.

Fun add on bit of kit
Fun add on bit of kit. Quite expensive for what it is, but does improve playability for the existing Gravitrax (which also was very expensive!)

Unusable
I finally went to go use this extension and the plastic immediately snapped when going to assemble it. All the other extensions work perfectly but this one is incredibly poor in build quality and not thought out at all. I am also way past the return window so stuck with it. I'd give it 0 if I could.

Doesn’t work very well
Doesn’t work as designed. Stops is the middle. Poor value for money.
