This is probably the most useful size of Really Useful box. I find with the 84 L versions you have to dig to much to find things. 64 L is good for a large amount of junk, but these 9 L are perfect for a few bits you need to keep out of reach of a baby e.g. HDMI cables, remotes, headphones, stationary, etc.
With regard to quality, these stack really well and are more sturdy than most other plastic boxes. They do not stack inside each other (of the same size) as the sides are vertical. Also, you can get little pegs to seal them, but I haven't tried to see if this makes them childproof.
