I just installed Ring Pro in my house. The Ring device, I believe the voltage regulator that plugs into the doorbell didn't solve my connection issue with the phone app. I purchased and installed a better quality doorbell transformer which resulted in an intermittent buzz and ring throughout the day. I installed a new doorbell and hooked up a ring voltage regulator: the occasional buzzing and ringing of the doorbell fixed it, but it kept disconnecting after a few hours, requiring a breaker reset. I removed the ring voltage regulator and plugged in one of those resistors and no issues with occasional hum, intermittent ringing and disconnection. I really only need one of these, now I have 99 extras. This resistor is also heat resistant. YouTube videos recommended this fix and IT WORKS! YRMV.
