Review on SCS Direct Building Bricks Connectivity by Adam Gechem

Perfect! No deformation! Works perfectly with the Lego brand (Duplo also works). I'm not sure about reviews where people say 1- they don't work with Lego, 2- they don't fit exactly, 3- they don't match. Good. 1-They work with Lego, 2-They fit snugly, 3-They line up perfectly (use a little common sense when placing them. If you glue them, connect the edges to existing Legos so they line up after the Dry to fit exactly. Use a flat surface when using them. Of course they won't level properly if your SURFACE is uneven. Duh). I made a beautiful lego table for my son and he approves too!
