Many years ago, I had 2 of these products installed at home from another seller. I bought 2 from this seller. The new one require more clicking force as compared to existing one. Still acceptable. However, one of the new one doesn't seem to work well even after using for more than a week. Only certain angle can turn it off. Cannot anyhow click to turn off. But turning on has no issue at all.
This product definitely can help save water. Rating : 2/4 May 29, 2020
