I like the transparency, but not the plastic
The storage bricks fit with the other large storage bricks and the transparency is nice. You can see what types of bricks are inside. The plastic is not very rigid and they can't handle much weight on top. The lid easily gets squished into the box itself and gets deformed (e.g., shipping with another product can be a problem--not all of my lids fit correctly upon arrival.) I would not make a stack very high of these if they're filled with Lego.
