My old steel rollers were about ten years old, and you never really notice how old and worn they are. What a difference! Quiet, smooth, and a lot less stress on the door opener.
Have had previous incidents that my Liftmaster key pad attatched to my Toyota car key pad in my pocket has unknowingly opened my garage door, sometimes overnight. Now I know from upstais in my office just by seeing a little green light that the garage door is closed.
But if there is a red light I just push the button on the monitor to close the door.
Great Product!
