Really nice to keep a pitcher in the fridge. The central cylinder is sized properly for the pitcher so no need to preweigh. No leaked grounds, but it takes a bit longer to steep than normal if you don't stir occasionally.
I've been liking this a lot, my one complaint is that the max grind setting (2min) isn't really calibrated to what the bottom tier is capable of holding. Since the grinds mound up in the bottom container, the grinds will start compressing back up into the burr and cause a jam. I sometimes use this to grind for cold brew, and it just means I have to be careful with multiple small batches.
How does the liner attach to the hamper?
