I bought this late on a Friday, a few hours later I realized this was a ring meter not a ringless one. My local utility only allows ringless. I contacted seller around 9pm, asked to cancel. My message was ignored, 2 hours later at 11 pm a UPS shipping label was created. UPS doesn't work weekends, so the package couldn't go out until Monday. To me this was a dishonorable move, upon reading my message seller created the label to justify not cancelling the order. Now I'm stuck with a boat anchor.
