Good product but…..
This was a present and was an additional part to the starter pack. Unfortunately it wasn’t in a package, so arrived with a large postage label stuck on the front, which won’t come off. The box was also damaged. Disappointed.

Excellent toy great for all ages.
I bought this for my grandson's and it is a great success I bought 3 sets put them onto my wall turned out the adults love it just as much. The stickies could be stickier but I used tape to help. Thanks very happy.

Doesn't stick to wall
I bought this for my grandson who just turned 6. He loves it. I gave it 5 stars because it keeps falling off the wall. It doesn't stick well at all.

The ball was smaller than i anticipated
The ball was smaller than i anticipated but i still give this 5 stars because i am sure i just missed the measurements somewhere. Plus the track actually does stick to the wall and various other surfaces quite well regardless of how many times i have removed and restuck them (maybe 10+ times by now without washing the sticky pad). The ball glides through the curves of the track smoothly and so controlled its as if the ball and the track were magnetically attracted to eachother. The loop requires a good amount of speed to be able to get through but its not difficult to get the correct angle and there are ways to do it with a curve too. I will continue to play with this until my child is of an age this would be safe for…… :-)

Great at first
My son used his Christmas present for 15 minutes and then lost interest. It doesn't stick to windows or walls.

Good concept
Sticky pads are not strong enough to hold the marble run up. Great concept thought just need to find a different adhesive.
