I like how easy it makes calculating time when you are working with multiple machines or jobs at once! Also there's no trial version so if something goes wrong they won't help much (but their customer service does seem good!). If someone already knows about using this tool box then great but otherwise its not very user friendly to new users who may need some assistance getting started in order use all features properly without errors etc.. But i'm sure others can probably figure out what we were doing as well because most functions work just fine anyway :) We have used them since high school/college around 10-12 years ago before computers became such an important part our business lives now days - back those times life was simpler haha!! I like how easy it is to use. There are so many different features that you can use. It's very user friendly. Sometimes if you're in the middle of something else, you have to close out all your programs before going back to this one. If you're looking for a tool box that will give you access to everything you need, then this is the one! You will not be disappointed. I'm solving problems that I didn't know existed with the help of my machinist toolbox.
