excelant product shipped as promised

I cannot say enough about the outstanding service received by Preferred Doors. My ordering of the door control for my garage was a seamless process and you guy never missed a beat. I was notified and updated about the shipment of my order, and it arrived on time in perfect condition. Thumbs up guys, this Veteran appreciate it very much!!

The liftmaster repair kit was exactly what I needed. The parts arrived very quickly and the repair went well. I had enough in the kit that I could rebuild my old part so now I have a spare if ever needed. Thanks for the great service.
