Your instructions need clarification.

To select the type of mailbox, the instructions indicate the dial is on the outside of the black box when the dial is actually on the inside. The instructions also fail to identify the 1 and 2 button on the receiver. And the cord could be longer.

Directions are a little confusing.

Victor Quintanilla

Should have ordered it long ago now it’s one walk to the mailbox

Harold Borland
Do far it has worked as advertised

1) Easy to install
2) Greater advertised range than other brands
3) Electric cord to base should be longer than the 20-22" that it is.
4) A hole in the back of the receiver to enable hanging on wall would be nice.
