The best part is that it's free for personal use, so you don't need to pay anything if you want to try it out first. It also has an online live chat feature which makes communicating with other users easier than using email or phone calls. I wish there was more tutorials available about how to improve my models. I am currently learning how to model complex shapes like cylinders, cones etc., but I have no idea where to start when trying to make something simple, such as a cube/cube. Also, sometimes the software freezes up while loading certain files. Sometimes this happens even after uninstalling all previous versions of iceSlicer. Try it out before buying! For me personally, it helped in creating 3D printing parts without needing any special tools aside from a computer.
