The software has been extremely easy to use and is very powerful especially when it comes to large data sets. I have never had any issues using this product nor do I foresee having any problems anytime soon. There really isn't anything that I dislike about the program or the way that it works. If you want something simple then this might not be your best choice but if you need something more robust than other programs out there then I would highly recommend giving this one a try. We needed something that could handle larger datasets so we used the GPU acceleration feature of this software which was able to make our calculations go much faster. This saved us time by being able to process our data set much quicker.
