Just do you can calibrate this review this is the first cut n' paste project I've had in over a decade. It took me about 2.5 hours to assemble this thing. I used the thickest card stock ink jet paper I could find over at the local office store. Attaching the base was the hardest part, this is likely where the product could improve the most. Also the top surface was not flat. They recommend in the directions to use some foam blocks cut into the shapes you need to support their models. After 2.5 hours this seems excessive.
All that being said I was able to use this with my players and they enjoyed it very much. A few oohs and ahhs where to be had. It prints out nicely and the pillars fold up very well. In the future I may use more such terrain.
