I stopped at #2. Those things are a pain to clean!
I wonder if her less than $5 coffee filter is leaching chemicals in her hubby’s coffee.
This is my main issue with many items on this list: reusable grocery bags should be machine washable (they shrink); Also fabric/soft lunch boxes and ice chests. We can put a probe on a comet but we can't make an insulated water bottle that can go in the dishwasher? Note to businesses: If it can't go in the dishwasher or the washing machine: TRY AGAIN.
Funny, we had one too and we also thought it was a pain to use and not worth it.
