I have one that came with our house. It has been a love hate relationship. Since I do all the repairs, been a pia for me. Usually lose a pump a year of some sort. I replace myself, so cost is somewhat reasonable. Kids like it and we have had some really good family time in it. Had a bday party with my 7 yo daughter last year. All her friends had a blast - so does bring some smiles.
Part of my issue, I have really bad water. Anything water related in my house has issues. Part of where I live I guess.
