The installation crew was on time, courteous and made quick work of installing the new opener. There were two items that I think could have been done differently that would have caused me to rate the Total Experience 5 Stars instead of 4. First Issue...when the crew finished the opener installation, I noticed the opener was plugged into one of my extension cords. When I asked about it, I was told the cord from the opener would not reach the closest outlet. I feel the crew should have immediately pointed this out to me, not make me have to ask why it was configured in this manner. Also, not your issue...but the documentation for the opener says you need an electrical outlet within 6' of the open...turns out that means 6' from the top of the opener. My electrical outlet was within 6' of the bottom of the opener, but not the top...facilitating the requirement for the extension cord. I moved the outlet after the crew left to remove the extension cord requirement...I just wish they would have pointed out to me. Second Issue...I found a few threaded bolts on my garage floor after the crew left. I feel they could have, or should have swept up any and all pieces leftover from the install. Again...I am very happy with the overall job the installation crew did, just think these little things make a difference in total customer service.
