I have to admit to love it.
This is the best value electrical certification app I have found. Once you get used to it and set yourself up some templates that you can copy and re-use for certificates it’s a breeze to use. I have had a few issues with the software but the support team respond to enquires quickly even out of normal hours. As a future add maybe where a submain is used the Zs value could be copied automatically from the circuit value to the DB it feeds. Keep it up guys 😀
