I am sorry its not going to happen this time.

**hugs**
I liked them both the same, I didn't htink the PISA was worth the extra money, you can speed the regular one up or slow it down based on what you need for a let down, the PISA has a pre-set time where its fast for a letdown, but not everyone is the same, so you may be turning it on and off to restart that phase, or vise versa anyway. jmho
