You can cut whatever you want at whatever depth you want. Of course, it's not of the kaizen type, but it is superior to Dewalt. With proper measurement and cutting, it fit perfectly in the Dewalt DS 150. I was quite satisfied. I fit the DCB 115 charger, 2x5ah, the impact drill driver DCD 796, the accessory box DT 7969 & DT 50050, and under the latter, as you can see in the photos, I managed to fit the 8 impact sockets from the DT 7507 box. Finally, I also added the 4 hole saws from the DT 71569 case. The gray mark you see is because I will replace this charger with the DCB 118, and there will still be some available space, although very little. As for ergonomics, the equivalent Dewalt is no longer available, and when it was, it wasn't as convenient as this one here. Now, compared to the price, I think it's okay because essentially you get 2 "sponges" for 19€, while with Dewalt you got 1 for 11€. With one sponge, you can do your job and keep the other in case you need it somewhere else or if something changes in your existing toolset.
