Review on 🔌 Insignia NS-AC501 AC Power Adapter - Black by Mike Ewing

Polarity not specified in product description. This ONLY works on devices that require a positive (+) center lug polarity. It is NOT reversible like some adapters. look at my photos BTW what I received was clearly something that was sent to someone else and previously returned as the cable wasn't boxed like new from the factory and the lugs weren't boxed like you would expect from the factory. The package also had a thumbnail tick on the closing flap where someone was already poking around, you opened it before I got it. If you sell items in an open box, you have a legal obligation to disclose that fact.
