I like how it calculates all my circuit diagrams for me without any errors or mistakes! It's very easy to use as well because there are no complicated buttons you have t click through when using this program compared too other programs out their such has ELCAD which can be confusing at first but once u get used ti its great!! There isn't anything i dislike about Elecalctm so far just wish they had more features available since we only need basic calculations done by them not complex ones though if needed then maybe another option would work better than what was offered before? This helps us keep track off our circuits easily while also calculating everything correctly from start till finish instead having multiple people doing each part separately makes things much easier especially during busy times where time matters alot.
