4 out of 5 starsFound out when stacking these more than 3 high the white tiles offset causing marbles to slow down. When you stack them they form a twisting polygon. I did notify the seller and he is looking into fixing the issue.

Thanks for letting me know! I should be able to get this rectified. For anyone reading this review, please know that I sent Bob some alternative parts for his trouble!

5 out of 5 starsQuality of this item is high tier. There is minimal stringing, no gloves and noticeable elephants foot and overall described how it was in the listing one thing you should watch out for is it chips the paint off your colored marbles and it does wobble quite a bit. But overall five stars.

Thank you so much for the review Jennifer! And good to know about the marble paint chipping. I hadn't noticed that. I guess those rainbow tubes have some grooves in them
