Product review (5 stars): it was an easy screw off and screw on for my fridge
Our water dispenser was flowing really slow so I did the usual things to check to see if the line was frozen. The only thing I couldn't test was the filter so I ordered one. I just received the filter in the mail today (thanks Prime). The box comes with one filter with a sticker covering the opening. After taking off the sticker I replaced the old filter with the new one. it was an easy screw off and screw on for my fridge. There was no need to turn off my water line before replacing. Easy off and on. I ran the water through the dispenser a few times. Immediately, I could see a difference in the water flow. No more trickling. It stuttered a few times which was due to some air in the line. However, after filling a glass twice everything was OK.

I would definitely recommend this product and will be purchasing another within the next 6 months.
