Wasn't meaning to pick on you, far from it. There's lots of novel ways to do things, and plenty of tool porn to sort through, especially on HM. Everyone here posts all kinds of enticing stuff!
Honestly, I was wondering if it was significantly better than a scale. If better and easier, that's good to know, if not, that's fine too. I always seem to have one tool holder less than I need, (even though I keep buying them if they are on sale) so I do have to occasionally reset the tool height. Not challenging your choice of purchase, or implying anything, just wondering if the ease of use and results are better or worse than the old fashioned way. Peace.
