I would add in the Festool and Bosch realm, the sustainers and l boxes get used in my shop. They are a treat and though I rarely take my tools out of the shop, on the rare occasion having my investments protected and interconnected is a big deal. With my Festools, I use the mobile carts around the shop and my second midi has my TS systainer on the top so I can pull it to the other side of the shop for sizing sheet goods down. My Dewalt boxes, Milwaukee bags etc.....I ise the Milwaukee bags as parts containers or for my lathe tools and chucks! Very useful. I used to have a lot of Milwaukee tools and I would get rid of those blow molded cases.
