Input:
The filter is good at what it does...filtrates. This is an inexpensive, small but not too small, water filter that is definitely worth the money. The replaceable filters themselves are common and sold at Amazon, Target, etc. That is a major benefit! There is nothing worse than buying a water filter that requires rare, extremely expensive replacement filters. That is why this filter and other Brita filters are the best for the money.

The major problem is that the flap where the water is poured from sometimes freezes close (even in the fridge). Flicking it with you finger breaks the ice and you can pour. This is a minor problem that happens only occasionally. Still worth the money though!
