Excellent quality, great fun. Already several hours into running marble competitions on it. Only issues are the import taxes to get it shipped to the UK.

My students & I are loving the IMR Grand Prix
My students and I are loving the IMR Grand Prix. I am using it to teach Pre-K through 6th graders about gravity, friction, probably, momentum, energy transfer, and so much more. Once put together it is sturdy. Not very easy to move around, so if that's something you need to do with it, I'd suggest building a platform with wheels. But if that's the only thing negative I can say about it, I'd say that's pretty good. I highly recommend!
