I bought this for the trees. I searched high and low trying to find affordable 3D trees and settled on this set.
Now I must warn you, these trees look great, but they take a loooong time to put together. I dedicated about an hour a tree to put together my small forest. Granted, I don't have the super-cool automatic cutting machine, but event the assembly itself took a fair amount of time.
Once complete though, these trees are awesome. I built 12 of them, half deciduous and half evergreen. I was concerned at first I would want more, but these trees fill up a typical flip-mat quick. If I ever do a truly big fight, like say a pool table sized, I might need more. I find putting just 3 or 4 of these on a mat does enough to say "FOREST" without filling every square inch with model trees.
