Bought four packages of these thinking that I'd need all four to make a circle. Turns out you only need three of these to make a circle. Track conducts very well and is easy to assemble. Great for quick and temporary setups on tables or floors. The track segments are very very slightly warped downward on each end, but not enough to be a problem.

This track fits together and pulls apart with little pressure. This is the perfect track to have when your layout is on carpet.

When we downsized the old layout didn't come ,but the thing I remember is how much time I spent aligning the tract and carving the homosote roadbed. Now I have a board for under the Christmas tree and E-Z Track makes it easy to align and connect the track. It may not be the track for your dream layout but it has good connectivity is easy to align and has an instant road be, so it works for me under the tree.
