I got my Blue Pearl (2007) model a month or so ago and love it. I returned a Dolphin Diagnostic that was total crap. I was surprised when I first ran the Pearl that after about 2 hours or so it stoped. I called them as they made a point in telling me that the Pearl did not have a shut off timer when I bought it. We discussed its color and the guy at PoolDr was surprised and said that I got a 2007 and that was a new feature that was added.

BTW I love the unit and would highly recommend it.
