Most of the pieces are OK, though some cuts are a little sloppy/not sanded down well/splintering.One of the 3-way splitters is awful. All 3 holes are cut unevenly, and 2 have some wood missing that probably broke off.Very poor quality control.Update:Here is how I fixed it:I reformed the edges with Hot Glue. To get them the right shape, i put a rolled piece of thin cardboard (like cereal box) into the circle. After adding a lot of glue, I used a box cutter to trim it into shape. You can use the hot glue gun tip to smooth over any rough edged.However, I then realized that the cutouts were on such an angle, the other tracks couldn't fit in with the edge replaced.I shaved down the entrance wood edge. Other teacks could fit rhen, but the rails weren't lined up 😂So, I shaved down the wood more and I added more glue.
