The Service was great. The garage door opener is silent which is great.
The system we PAID for came with a camera, an app, kind of like a Ring doorbell. The problem is the camera pin pad (outside)
Couldn't open the door. A mystery . Finally Door-co said they’d just install the older style pin pad instead of the high tech one with the camera system. The older pad works, but has no camera etc. Problem is - SAME PRICE for older zero tech replacement product. Less tech - no discount?

The Service Technician (Larry) showed up the next day (St Clair Township) and replaced both springs in an extremely efficient manner, then did an overall maintenance of the hardware on both Doors. We were extremely pleased with the overall experience and how proficient and personable the Technician was to interact with. Highly recommended.
