a bit tricky to setup at first and the instructions were a little lacking, but once setup it has been very easy to use and consistently provides great tasting water.

MERCHANT RESPONSE:
Thank you very much for your review! After checking our records, it looks like we communicated quite a bit and you had a unique "Chicago Style" faucet, which has a thread size which is not very common. I also did research for you to find the right adapter, which you said ended up working great. I will provide a link to this adapter in case any of our other customers reading this have a "Chicago Style" faucet:

So I assume the "tricky" part of installation was primarily due to your unique faucet threads, and not so much the instructions? If I'm incorrect, please contact me so I may address and correct whatever you feel was lacking in the instructions, as we want to ensure our customers are fully satisfied. As you may already know, we also provide free phone tech support if necessary. Thank you.
