The ability to customize your model according to what you need for surgery is great! I wish there were more options available in terms of customization, but it's still pretty good overall if all they offer are basic shapes like spheres or cubes as well as some simple colors (which can be changed).
Some people may not have enough experience using this software so maybe try before buying? It takes time getting used too because everything looks different than other programs out their - especially when trying something new at first since most things look similar from one program to another which makes learning difficult initially until familiarized yourself w/it better. Customizing my own facial prosthesis after having plastic surgeries myself was very helpful during recovery process by being able to see exactly where each area needed repair / improvement etc., without any guesswork required about shape & size beforehand; also helped me visualize results much easier once finished due to knowing exact fit prior vs waiting several weeks afterwards only find errors upon.
