r/BuyItForLife
ViewTop Criticism
+1 pts“I know the Toto C5 and C2 are well regarded. I had the C2 and found that the warm water ran out pretty quickly. I now have the K300 which heats water on demand. All of these have heated seats. I just don't like how small the actual area you sit becomes. So, for men, I don't really have a seat that I'd recommend.”
