Product review (5 stars): No lint-my Lady, perfect!
These work very well. WAY better than the wire mesh similar lint traps.  I have installed a grey-water recycle system that runs the used washer water to our lawn and plants in the yard. This lint trap does a great job placed on the end of the hose keeping the lint from being deposited all over our yard. I really like that it has an elastic end which makes it easy to remove and clean, then slip back on again.

If you are using the lint trap from the washer directly to the drain, I would recommend adding a tie-wrap or cable tie on the neck of the lint trap so it doesn't accidentally come loose and drop into your drain pipes. Check it monthly, because it does a very good job catching lint and will fill up fast, especially if you are washing things like flannel sheets, or new towels.

Fits both at the end of a hose, and a standard washer drain hose. Any larger than the gray hose pictured, the elastic will not fit.
