Easy install and filter change

We got one of these as a replacement for the internal filter in our refrigerator. The product came with all required hardware / parts and installation was extremely easy.

Pros:
* The filter we chose is good for 24 months or 16K gallons; WAY better than the internal filters we had.
* We haven't noticed any odd flavours or smells in the water post-filtration.
* The filtered water is clean and tastes good.
* Filter swap is easy.

Cons:
* None so far.

Works great under the sink! Must buy extra pieces

I don't use this for the fridge. I use it for the sink. I have a spray faucet so I couldn't get any other filter; I had to get one that attaches directly to the water line. I had to get extra pieces from the hardware store to make this work but I did it! It did leak a little in the beginning but now it's all good! I could taste the difference in quality before and after. Btw I use it standing up.
