susan easterday: I’ve had this garage door opener for 4 years now and I want to say it has worked flawlessly since I’ve had it. However, the best feature has got to be the phone App. It controls the door to open and close from anywhere, it ties in with ring and notifies you whenever it opens or closes. I all to often second guess myself after leaving home if I closed it. Just check the app and you can rest assured. Great product!

Kranti Biswakarma: It's been a month now and I'am satisfied with the product so far. It is powerful enough for a single garage door and not too loud either.
Bear in mind that the wifi works only with 2.4G band, so if you're using a WiFi range extender, make sure to create a 2.4G channel and connection will work fine.

Roberto: Esta muy bien equipado, funciones wifi muy bien, fácil de instalar, sincronizar etc., muy silencioso. Solo una observación no usa cadena, utiliza una banda plástica por lo que podría no ser util para accesos que no sean un protón típico que sube y baja … viene con el riel del tamaño de un portón estándar por lo que si requieren uno más alto, requerirán de más riel probablemente y es diferente a los de cadena

Steven P. Spinella: This is for the belt-driven, wifi-enabled unit without a camera. I am totally pleased with my selection, both as to brand, and as to this particular model. I have several chain-driven units installed elsewhere, and they work well, but this works better, and I think the price differential was quite reasonable.
Chamberlain, same company and interoperable with Craftsman and Liftmaster units, was the pioneer of the electronic sensor, now required more or less universally across the US. Other manufacturers use their same tech in the sensors.
The belt drive is quieter than the chain drive and less likely to fall out of adjustment. Follow the instructions carefully to get the tension right--it's not intuitive. When it's correct, it should vibrate at a visible rate like a lower frequency plucked string.
The instructions are not easy to follow--basically there are a set of different colors on the instruction page, and you follow the instructions in sequence by color, but there is no place that gives you an overview. That's probably why they've also given several youtube channels free units to review, resulting in instruction videos of varying quality. Still, it can be installed by...

Time For Lunch: ***Edit: we have had this garage door opener for 1.5 years now and we love it! LOVE the phone app!!! We just had to replace the garage door opener on a rental home that we have and immediately went and ordered this same opener for the rent home. The renters also LOVE this! It is so quiet and the phone app will definitely spoil you!***

We had to (reluctantly) replace our garage door opener at our home. This opener is the new version of what we previously had. My husband researched these for a while before he decided on this model. It was easy enough for him to install without any major issues. He installed it during a Saturday afternoon so it wasn’t too time consuming either.

This garage door opener uses two spiral CFL light bulbs on either side. It is considerably brighter than our previous unit which is nice. The bulbs did NOT come with this garage door opener. It would have been nice if it did include bulbs but it states on the box that it doesn’t come with them.

This garage door opener is so much quieter than our previous unit! Substantially quieter!

We have Home Link on our vehicles and sometimes they are tricky to get the garage door to sync...
