The size of the container makes it easy to grab with one hand, even when full, which is always handy if you place it on a high shelf. The lid feels sturdy enough to last for a long time and its shape makes it ideal for (confident) stacking. It is made of high quality plastic that is easy to clean. Washing the lid requires a bit of disassembly, but it is definitely not rocket science.
The only downside and hence only four stars, is that the plastic used is prone to static electricity. So if you use the container to store powder-like substances (like flour or ground coffee), they might slowly creep up to the brim and to the silicone seal, where they stick till washed.
