Product review (5 stars): I've had it installed for about a week and everything seems to be working just fine -- no complaints
I bought this to replace a GE filter for my GE Arctica water/ice system.  I don't remember what I paid for it now, but it was at least $10 less than the GE replacement.  I've had it installed for about a week and everything seems to be working just fine -- no complaints!  And it arrived promptly, so win/win!  I don't track how long they last (a light on my fridge's front panel tells me when it needs to be replaced), but the filter came with stickers to use to record the install date so I will be curious to see and hope it lasts about 12 months like my GE ones typically have.

UPDATE:  Just bought my second one of these at the end of December 2015, so I think the first one lasted about 13 months.  I am again very pleased with this filter and its price.  We go through a lot of ice and water and the price on this filter is lower than the GE brand, so no complaints!  Will definitely buy again and again.
