Product review (1 stars): WARNING: WILL COAT YOUR ENTIRE HOUSE WITH A SUPERFINE LAYER OF LINT
After over a dozen uses, my entire house is coated with a super-fine layer of lint! It is easily visible EVERYWHERE, and is a shocking amount when you wipe it off. I had to quit doing laundry for a while and wipe my entire house down. My dryer has a very effective lint-trap system, which kind of makes it worse. Only the finest particles get through the dryer's two-stage filters (and probably only 1% of total lint), which are harder to clean up. (And can't be good to breathe!)

The water does absolutely NOTHING to capture lint. I left the same water in for about 10 loads one weekend, and it only had a few lint particles on the bottom.

The product itself is an absolute rip-off. It's just two small plastic buckets, with a crude "snap" system. The problem is, the bottom "inner" bucket is too large in diameter, so the top "outer" bucket can't properly fit over it in order to snap. Without being able to snap, it is easily knocked over and your water spilled. Some con-artist is making a fortune off of this "product".

And if you really stop to think about how this works, you'll realize it can't. When moving air strikes a surface, the bottom-most layer forms a "cushion" which most of the other air just slides over. So only a fraction of the air makes any contact with the water, and even then, the concept of surface tension should inform you that the air doesn't enter the water, or provide any way to "grab" the lint. You might be thinking, like I did, "well the lint is heavier and so inertia will cause it to plow through the turbulent air at the bottom and land on the water, then sink". Except in reality, it doesn't actually work that way. I suppose if you had a crappy dryer that didn't filter out the big stuff, then that might still work for the bigger chunks. But empirically, it DOES NOT WORK for the super-fine lint, which in my case is all of it.
