Dad endorses Nat Geo magnetic marble run as hit gift
Nat Geo magnetic marble run was a huge hit for my 3.5 year old. He loves it. My 8yo nephew also couldn't get enough of it. It really is for all ages. Magnets are super strong. Works great on our refrigerator.

Kickstarter backers complain about retail availability before fulfillment
Just got an email that my Kickstarter Marble Run is now being sold in Target while I haven't received mine yet. Two years late and they're selling it at retail before fulfilling all backer rewards. The instructions are only QR codes.

3D-printed marble run project shows general interest in marble runs
My marble runs finally completed. Mesmerizing! Designed and 3D printed over months. Not product-specific but reflects community enthusiasm for marble run toys.

Dad recommends Nat Geo over PicassoTiles with compatibility note
We have the National Geographic one and it's dope. Got it on sale for $25. Awesome reviews online. PicassoTiles makes a cheaper set that's compatible and also gets great reviews—we'll probably add that for more pieces.
