Customers say
Customers find the transformer works well with Ring doorbells and is easy to install, taking just a few minutes to hook up. The voltage output receives mixed feedback – while some say it provides plenty of power, others report high voltage levels. Moreover, durability is a concern as units fail after one day of use, and the noise level varies between being quiet and producing a loud humming noise. The transformer serves as a good replacement for older models, though opinions on overall quality are mixed.
