What is the appeal of these compared to just getting a 10 inch under the counter filter set? I have a double filter set, with two different multistage filters. The water is extremely well filtered and it's relatively cheap to change the filters a couple times a year as per manufacturer recommendations. It took me 35 minutes to install, but it's been running fine for years.

You make a good point. I'd imagine the large upfront cost + the effort required to install.

It is not expensive - even when compared to pitchers -, and I guess perceived difficulty, since it is not hard to install.
