Product review (4 stars): Seems to work fine. I haven't had it scientifically tested
Seems to work fine. I haven't had it scientifically tested, but water comes out, and it fits my fridge. Just went through my first one, which saw heavy use during the 3 months it was in service. So I'd say that it could conservatively last you the 6 months that is quoted. Ordering another one now.
