That the product works, and I don't get any phone calls/bother from the company about it. I don't get hassled about the product, we all just let it work and let me go on with my life without a lot of fuss about it.
Salt delivery is timely and drivers are very professional. Repairs, if needed are completed in a timely manner by qualified technicians. You can purchase salt for less at several locations, however taking into account the delivery service, works well for us. Also like your email billing process.
I like that when I call, the office staff is very friendly and don't mind me asking questions when I'm confused. I appreciate them coordinating and having the right people come to my house to fix any issues that may arise in a very timely fashion. The delivery personnel that come with my softener salt are always friendly too. All around good people!
