There have been many reports of problems with this unit,mostly on the psa forum. PSA has updated their forum two times recently and most of the threads complaining about the ppp have been lost. What percentage of production units had or have problems I do not know. The complainers tend to speak the loudest but many report no problems and love the product.
I would suggest looking into the Audience power conditioners,my personal favorite,but if you do decide to buy the ppp I would suggest buying one with atleast a year left on the warranty as the warranty is fully transferable.
