Probe Loop Detector

GENIE 3850R works very well with my GENIE receiver #315390R2 that I have operating an old Chamberlin opener. The receiver was not included in the installation instructions but they were the same as the first (A) instructions you sent. You probably know all this but just in case not I thought I would comment anyway. Thanks

Fast delivery and friendly customer service.

It has been a pleasure working with your company. I ordered a part and it shipped almost immediately. I received updates when it was out for delivery and when it was delivered. Very unusual to see this kind of service today.

Great pricing, free and RAPID shipping along with great communication; you can't go wrong with Preferred Doors! If the need arises I'll be a repeat customer for sure. L Kargol
