Bests & Worsts Reviews from Amazon

Though this unit works well, it has a very bad design flaw that any buyer considering it should be aware of. When using it as a portable getting power from its internal AA batteries, even when you shut the unit OFF with its ON/OFF switch, the four batteries will self discharge to dead in about a week because the unit still draws current from the batteries even when shut OFF. I considered my unit to be defective because of this problem but when I contacted Philips support to request a exchange unit under warranty, I was informed that this battery drain was normal and that I needed to remove one or more of the batteries when not using the unit to prevent the batteries from going dead. Dumb, dumb, triple dumb design flaw in my opinion! Why even have an ON/OFF switch if you must remove a battery to really shut it OFF!
