I had been searching the internet for an earthwork takeoff system that I could get up and running on in a short period of time at a reasonable price point. I was downloading and trying various programs when I ran across Kubla Cubed on the internet. During the trial stage I was amazed at the ease of use and the practical steps of performing the takeoff. The software was designed to think like an estimator, in a logical step by step process. Once I discovered the incredible low price, I was hooked. This software meets or beats software priced at 10x its cost and it is incredibly accurate. Amazing value in a powerful package. Paul Sciotti, USA
