It was very easy to install. I noticed my skin felt less dry after first use. My hair was more managable after the second use. The water felt so soft on skin and no chemical smells from the water. The water didn't sting and burn like it did before the filter. I used a lot of shower filters before with no improvement. I'll be interested how often I have to change the pads,etc. to keep it working this well. I would recommend it to others who have problems with water quality.
