Great so far very easy to install

Easy ordering for filter replacement

Filters were straightforward to order and easy to find the right parts. Delivery was fast. Only criticism might be that there was not an option to buy a 1yr supply, but it’s not a big thing to store under the sink

Good product

I ordered a set of filters. Delivery was very fast and the product works as expected. Thanks for the good service. 👍

Order came quickly. Everything was ok .
