Good delivery time. Item was as described.

The new sensors fixed my problem. Great product Great Vendor

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.

As the garage door is the way I come /go in my day, when it broke last week, in the cold, I moderately panicked - - then my hubs found Preferred Doors! Even w/regular shipping it arrived quickly, & the part easily installed (thx hubs)! The email notifications were a godsend, tracking the hours til I could click my opener again! Thx Preferred Doors!
