Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Simple to program, Worked first time

Our LiftMaster wireless keypad failed after a repairman damaged it while making repairs to the frame around the garage door. I ordered this unit based on the positive reviews from many, many Amazon customers and as usual, the crowd has nailed it.The unit was delivered in great shape. It came out of the box with a battery installed (nice). And the instructions for programming it to open the garage doors were so simple and easy to follow, I had the thing working in less than 15 minutes. That was a good thing since it was cold outside when I installed it.Important - We have LiftMaster garage door openers so getting this wireless device seemed like a no-brainer. The ease with which it all came together proved me correct.Highly recommended for anyone looking for a LiftMaster compatible keypad.
