Product review (1 stars): Easy to attach but water catches back into washing machine for Whirlpool Cabrio
These lint traps are easy to attach, in a similar fashion with a zip tie to other metal types of lint traps.

However, upon attaching I found that the water was unable to freely flow from my washing machine water drain (Whirlpool Cabrio) and eventually caused the washing machine to pull back in the water in the machine and left the clothes still dirty.

To me the lint bags needed to be quite a bit longer to be universally useful for any washing machine, so I'll probably go back to the metal type.
