Bought these as an addition to my other Connetix; they make the Connetix more versatile.
This is a really cool ball run! Lots of fun. The size of the balls is also nice as some marble runs worry me so it’s nice to have the larger size of the balls and you can do so much with these.
This ball run is much stronger than other brands. Holds just up much better and is an excellent addition to the mega pack!
Our 4-year-old granddaughter loves the magnetic tiles, but the tubes are a total bust. The adults have a hard time assembling them, especially since you have to try to hold the two sides of each tube together while putting them in the slot, and they keep slipping away and feel like they will snap. Once assembled, our granddaughter can't even get them apart - that is also difficult for the adults to do. Also, there are many shapes of tubes, and no diagrams are supplied to show how they can be connected - just a few pictures that are really only sales material.
While Connetix is a little more expensive than other brands, this is the strongest magnetic tile brand ball run I could find. I didn't want to deal with collapsing runs, so I went for this set and we've been pleased so far!
