The box contained all that is needed to install. The installation difficulty is dependent on what gets in the way under the sink. The sink space, disposal, and sink shape added a lot of time to my install. There were no leaks but it needed to run water longer than expected to get a good clean taste from the water. The pour is slower than desired but probably good for a 3-filter system. I expect it to be easy to change the filters but haven't done that yet. The product is used to provide clean water for cooking and rinsing in the kitchen.
I purchased the 3 stage undercounter filter and could not be happier! The quality of the water is wonderful and the taste is much improved from standard city water. I upgraded from a Pur filter and the difference is very noticeable. The install was easy and all the needed parts are provided. We are very happy with our new filter system.

Pros: Clean taste, Durable, Easy to clean, Easy to install, Long lasting filter
Good and simple water filter system. Water taste a little different from our RO system before but this one you don't need to wait for the water when you want to fill for example a pot. Easy installation.
Pros: Clean taste, Easy to install, Very Good Customer Servic
Chalky taste until we ran water a second time for 10 minutes. Great taste since then. Use for drinking, cooking and making ice cubes. Replaced an old broken Everpure system. Biggest criticism is that the water runs too slowly. This needs to be improved.
