Input: Overall, this shower head seems okay, and the filter is great. However, when I turn the water flow up or down, etc., to soap, etc., the water can become unexpectedly scalding or freezing. It takes a long time to adjust it to the former temperature. This is a deal breaker for me. I have a small shower and the situation involves a lot of ducking and craning to avoid unpleasant temperatures.
