Product review (3 stars): Cheap Materials - Mice think they are yummy! - But You Have No Choice
The mice, driven in by the crazy winter, have chewed through two of them.  That's two times finding a deluge in the kitchen. Twice pulling everything apart, twice mopping and drying and putting it all back together again. PITA.  The second time I carefully wrapped much of it in duct tape, sprinkled some peppermint oil around, put glue traps and a poison trap back in there, and stuffed steel wool in every hole I can find. So far, so good.

This could be engineered out of much stouter stuff, but right now it is THIS IS THE ONLY REPLACEMENT PART ON THE MARKET. Why? Because everything is made to fail.

tl;dr if your old one sprung a leak, reinforce this one BEFORE you install and rodent-proof the f%@k out of it.
