"Good little buy and does the job"
This is a good little bits-box, sturdy and seems robust. The trays are good, although anything under a few mm in size may leak into the next section as the removable spacers have a small gap in each corner next to the floor of each tray - but the tops of the spacers seem to sit flush with the lid.
The removable spacers allow to increase the compartment size from left-to-right only; i.e. (approx.) 1" x 1", 1" x 2", 1" x 3"+
I'm using it for electronics bits, resistors, diodes, and things like that, and it does ok (minus the gaps in the spacers).
9/10 - Loses a point because of those gaps.
