I have had my Toto for 15 years. It was sent in once - about 5 years ago - to be repaired. They sent it back with all the hard water deposits cleaned off and looking and working great. It just recently got undependable and I have purchased another, the one with the e-water. I am excited to have my husband install it and use it. He is not as excited as me.
I also have the Toto travel bidet. It works well, but I could not use it in a public restroom with stalls as I need to fill it at least twice to get clean. I would not want to travel without it, though. The butt gets way too sore if I have to wipe every time. Another helpful thing is to buy your preferred TP once you reach your destination. Motels... always buy the cheapest stuff and it tears me to pieces.
