EASE TO PROGRAM

This unit works from 3 regular batteries, wirelessly, just like regular gate opener remote. You mount it anywhere 50 feet around your gate and it will work just fine.<br />As addition for this unit you can get a metal cover that helps to prevent too much rain getting on the keypad so if you live in place like Seattle or Oregon you may consider that.<br />I was expecting keys to be little bit softer but it's ok, at least I know for sure if I really pressed it.<br />Replacing batteries is not harder than in regular wall clock - you can just unscrew two bolts and get it done. The body of the unit made of metal so it is kinda vandal proof. For this price it's a great item.<br /><br />If you want to go fancy you can get WiFi door bell that had camera and calls your phone to open the gate.

this is the second one I have ordered. The first was defect and was returned without any problems. I wonder how long the batteries will do it... nothing is been said about that in the documentation. Hopefully it will last for a while.
