I like the ability to get information from any project and transfer it to any other project I am working on. I like that it has a lot of information that is very helpful. I dislike having to keep reentering information and having to copy and paste. It is very time consuming. I would say that it is a good program but it is better if it had more information included in the estimates. I use it to calculate my bids and to get estimates from many different companies. I like its ease of use and it offers many features which makes this program very user friendly. It's also compatible with other programs such as Microsoft Office Suite so there are no problems in transferring data from one project to another. Nothing at all! This product has made my job easier by providing me easy access to the information needed for each jobsite.
