I found this very easy to set up and use. The filter was easy to install and use. It is said to dispense 2 tanks before using. And has made my tap water taste better as the tap water I drink isn’t contaminated but does have chlorine taste. It’s easy for my 8 year old to use too. Has made it easier and a fun task for him to drink more. 4 out of 5 stars because it does make noises while dispensing water.
