Review on 🔌 Giom Lightning to 30 Pin Adapter, MFi Certified Male to 30 Pin Female Connector Converter with iPhone Lightning Charger Cable Cord Compatible for iPhone 12, 11, X, 8, 7, 6P, 5S, 4S, 4, 3, 3G, iPad, iPod (White) by Mark Sutovsky

I bought two of these for two different devices (speakers with an older generation iPhone dock). One worked one day, the other two days, then they died. If they didn't work right out of the box I would return them for a refund but when they initially worked after testing out of the box I threw the box away.
