I loved it, I bought it to put more fun on my marble run and it really is amazing, it is true that it is slow but I just change the configuration of the gears and it works great, I totally recommend it. Read more

Bought this thing with the hope of it adding a fun element to our boys marble runs. FYI- this thing is slow! I thought it’d be NEXT Christmas by the time a marble made it to the top. We almost bought two and I’m glad we didn’t. My boys want to “take a break” from it because it’s not fun or fast to keep the action moving. It also feels very cheap compared to other marble genius products. Pass by this one! Read more

The lift is easy to assemble as long as you do it one piece at a time and have the screw pieces higher than the tube. You should check the rotation of the screw as you assemble the unit. I bought 2 extension sets for the lift as I had a very tall (37 inch) starting position for my marble track. I send 16 marbles at a time down the first section of the marble track, and there are spheres and tubes at the start of that section. The lift sends the marbles down with enough time between marbles so that they do not cause any jams in the alternating spheres. For me, this lift is wonderful and a great addition to my marble track.

The extension took it from unusable with a marble run to actually usable. Would be even more perfect if there was 1-2 more sections. Read more
