Yes there is static cling on the walls of the plastic grounds box, but that’s what they make brushes for!

The one annoying thing, that is probably true of all plastic grind bins, there is static cling that makes the ground coffee stick to the sides and can be messy if you're not ready for it and don't tap it down before opened

Lots of static cling inside the bin.

They recommend tapping the back gently before removing the bin to clear the exit port, but due to the static cling effect tapping is useless.

I have to hold the bin over the sink to get the coffee out, as the static cling from the plastic causes the coffee to go everywhere

Just too much static cling

The motor is loud and sounds cheap, and it retains quite a bit of grounds, up to 2 full grams in some cases (16g in, 14g out with my latest grind), so not super great if you're using different beans for espresso/drip/etc - especially since it sounds like it's going to burn out and set fire once the hopper runs out... and it does NOT know that it should shut itself off, so be ready to do so manually when it whines
