Part arrived within a week with USPS tracking and it fit perfectly to replace the old broken part. I don't have to open my garage by hand no more. Good stuff, I'm planning to buy another coupler as back up.
I had a LiftMaster garage door opener system that was obsolete. It was a chain driven AC motor system. It has been a reliable door opener. The remote control failed on the unit. I could still open and close the door with the manual control inside the garage. I decided to buy a new opener since the one I had was obsolete and I didn't want to invest in the cost of repair of the old unit. After installation, I operated the new belt driven DC motor unit and was extremely pleased. This new opener is 10 times quieter than the old chain driven system. I am a happy customer and would recommend this unit to anyone in the market for a garage door opener.
Being a pro door tech, speed accuracy, and reliability, is what can make or break you. These guys met my expectations, and will definitely do more business with them. Thanks fellas!!!
