Product review (5 stars): Great filter, lasts 6-months, easy to install.
If you read and install via the instructions, it's a breeze.

Takes some time to soak before first use, then the actual install is about 5 seconds, simple push & twist.

Filter lasts about 6-months on average before the filter light comes on for me.  This will all depend on your local water quality though.

No problems with seller.  I think I got the filter in about 3-4 days.
