I have had the same toolbox for ~30 years. I knew exactly how to lay out the tools to get the trays back in and get the lid to close, which honestly was a pain but was just how it worked from the beginning. After the latches failed, I started searching for a new toolbox and spent time in retailers trying everything that I could get my hands on. I finally settled on this product and I am very pleased. MOSTLY because there is a pouch for everything with plenty of room for more stuff, and I only have one layer of miscellaneous tools laying in the bottom of the bag. This leaves room for those few tools or batteries that you normally don't carry every day, but will need for the current job. There are rubber feet on the underside which really makes sense, and the handle is great. I have not tried the shoulder strap, but I'm sure it will come in handy. My only caution is this; you will load this with too much stuff!! I moved everything from my old toolbox and then decided that I could carry EVERYTHING that I might ever need. The product didn't seem to struggle, but my arms and shoulders sure did. I would recommend this product to anyone that needs to have lots of tools for varying needs at your fingertips.
