The best thing is that it's very easy to use for beginners since there are tutorials available online as well so you don't have to worry about anything. It also has a lot of features which makes it good when compared to other similar softwares out here. I think if they can make some more enhancements like adding new tools or better integration with 3D printing then it would be perfect. I am using VLAB works mainly because it provides me access to several different simulators along with my CAD files and allows me to do everything from one place. This helps save time and effort.
