I recently used Eigen software for a project. The installation process was very straightforward and the software was easy to use. The software boasts a lot of features, but I found many of them to be redundant. The documentation was comprehensive and accurate. I found that the software ran very smoothly and was relatively bug-free. The support team was also very responsive when I needed help. The cost of the software is reasonable, but I think it could be improved with the addition of a few more features. So far, my experience with Eigen has been mostly positive.
