The best thing about this tool is that I never ever have any issues with my CAN busses anymore. They both work properly! And they do not fail me too often. If you are working on anything related to communication protocol stuff like network cars or something else than you should definitely use this program. This works flawlessly! Nothing bad at ALL! You MUST download it if your dealing with networks. It's very helpful for keeping things running smoothly without having to worry constantly about errors caused by faulty CAN Buses. I like how easy this tool was use compared with other tools i have tried before (i've been using them since my first introduction into communication protocols). The interface could improve but its good enough at what you need! Its very useful while developing an application or just testing your own code/protocol implementation because there are many features included which make things easier than having to write everything by hand yourself!
