This arrived on time in good condition, and it does what it is supposed to do.  I only wish it lasted longer since it is so expensive.  We drink water out of the fridge several times a day, so it gets a lot of use and lasts about six months.  As far as I know, nothing else will work in our refrigerator, so we don't have any choice but to pay for it every six months.
