The product arrived in brand-new condition, in its box with everything included (unit, manual, 9V battery, two mounting screws). Clear instructions for entering (on the keypad) the dip-switch positions of my garage door opener, and for changing the 4-digit keypad PIN. Worked first time. This unit is virtually identical to the previous unit that I am replacing, right down to the spacing of the mounting holes. I am so happy to have found this on this site.
