Review: Produt it works on the Ring camera. - Wonderful product, straight wire, it doesn't matter which side is which, both side does the same thing, easy on installation. The wire is very long. It would have been better if the wire had been 10' shorter. But this transformer keeps the Ring camera charged all the time. Love it. very functional. connectivity is eased.
Review: Never have to remove faceplate again!!! - Best part is you never have to remove the fragile cover again. I’d broken several over the years. Now have the screw in and no need to remove faceplate!!! Works as described. Battery stays in unit so if a vandal cut power line unit still works. I cut the line to length and held in place with staples. Easy to install and when you check battery in app it will say hardwired. It also slowly charges battery.
