Not the quality I was expecting for the money I paid

Purchased the Marble Run kit the plastic is very brittle and scratches and tarnishes easily as compared with the one from Magnetex. The size and magnets are compatible with the Magnetex pieces. The IMAGIMAGS magnets might be slightly stronger but the plastic is very fragile for the price. It makes playing with the plastic less fun as one is always very cautious that you might break it. The marble run is also not easy for kids to assemble maybe more designed for adults.
