水閘分岔（已塗裝）附錨定磁鐵

The anchor magnets click together securely, making these sewer junctions way easier to assemble than my old pieces. I finally have enough turns and intersections to build a sprawling underground network without running out of connectors.

I was pleasantly surprised by how many pieces you get in this set—it's more than enough to map out a full sewer network. The anchor magnets are a clever touch that keeps everything from shifting during gameplay.

The painted detail is decent from a distance, but up close the edges look a bit rushed. Anchor magnets hold well enough, though I wish the set included a few more straight pieces to balance out all the turns and intersections. Still, it gets the job done for a basic sewer network.
