Solis Coffee Bean box Black

is just a great knocking bin, it does its job well, easier than walking to the box every time

The plastic is solid but a bit hollow, if you are trying to empty your coffee grounds this the plastic shakes a bit so it can be a bit noisier than other more solid counterparts.

This is no more than a plastic container with a stick. The knocking makes way too much noise. This is due to the wood and the fact that the tray has a hard surface. Bought another brand after two weeks. With a rubber bottom and a stick made of a sound-absorbing material. Makes a big difference.
