I like that it allows for multiple tests to be run at once, as well in one test you can have more than 1 device connected/checked (such has HDMI or DisplayPort). It is also very easy use when doing manual checks of my devices with no errors found! There are some functions which could do better such having an option where we see what's going wrong instead just getting dumped into another page without any explanation why its not working properly - but this might come from me being used too much other tools before switching over so maybe they're already there? But overall i would say go ahead give them try if your looking for something simple yet powerful toolkit :) We were able check our monitors after applying updates using their own drivers rather then relying only upon windows automatic update feature by running automated system stability checking process every hour during peak traffic hours etc..
