I have a culligan water cooler. Ive had it for like 20 years, couldnt live without it. Increases my water intake, and it tastes great. Also i get my water delivered. Extremely convenient. Customer service is always warm and welcoming and I've never had an issue that wasn't easily solved.
At the age of 80 I no longer want to carry bags of salt downstairs. Culligan keeps track of my water use, calls ahead of time, and delivers promptly. They always answer any of my questions.
