Both mine and my dads were working fine, but I replaced both anyway as this has several advantages over the standard ones that were installed in our houses..
Belt drive so much quieter
The wall button has a motion sensor that automatically turns on the lights
The wall button has a display that shows the garage temp
It has wifi so you can control the door anywhere, but also get notifications when its opened/closed
Has better range for the remotes (works further away in my usage)
Comes with outdoor keypad (my dads door didnt have one so he does now)
It has battery backup so it opens even when the elec is out (sure if you're on the inside you can just pull the release cord, but this helps if your outside too)
