It's a great business move. Make $30 on a DIY doorbell, then spend three hours dealing with the customer because it is "too sensitive" and sends them alerts all night when large trucks drive by the house. Replace the device, because it must be defective, and new device performs identically to the original one.

In the end, you have a customer who's unrealistic expectations cannot be met.

(yes, I'm sure it is my fault because I didn't properly set the expectations, and educate them enough about the unrealistic commercial they saw on TV)

On the bright side, pointing out to them that the Ring Bell that the ELECTRICIAN will be installing is dependent on a good WiFi system, and an additional access point would be a good idea, leads back to our line of work.

(in know, lots of run on sentences. i'm in a mood)
