Product review (4 stars): Tired of old mineral build up
I finally had enough of the disgusting looking tray we inherited in our rental house.  No amount of cleaners or cleaning would get it clean.  Turns out just buying a new tray was a cheap and easy solution.  I wish it was designed better, so it would actually stay in place - it just slides right into place (and out of place), but other than than, served my needs perfectly.
