We have the Genie Excelerator on 5 doors. Had them for 17 years now. Still like them. They are screw drive and not very noisy. They go up very fast and get out of the way. I don't like to wait on the door to get out of the way. They go down at the normal rate. They also vary the speed, for example, if it thinks it should be hitting the limit and it hasn't yet, it will go very slow until it does. This only come into play when you have messed with it such as disengaging it from the track; then it has to re-find the stops again. The one door got the most use as it was used as an entry to the home all the time. I eventually moved it to the shop building and put new ones on the home garage. I really like them.
I have 8' tall doors and they require an extension screw for the extra foot. Once got an extension that was cut 180 degrees out on the screw so the threads would not line up. Had a heck of a time convincing Customer Service that was the case. They were good and sent a whole replacement set just to make sure they matched. None of the Genies that I can tell and WiFi.
I can't stand the Sears junk I had years ago. Very noisy, crappy units. I could have been just since they were the entry level units.
. I want the WiFi since I could be in any of five different vehicles and I always have my phone with me to use as the opener.
