Easy to install and program.
I bought this opener to replace my old “non smart” motor that was not compatible with myQ wifi hub. This motor is very quiet, easy to install and program, functions exactly as described and super easy to connect to wifi. For the money I think this is a great quality purchase.

Packed with features, for a GOOD PRICE!
Bought this opener to replace a 20+-year-old Craftsman that bit the dust. I've installed all of my previous openers, but paid a local company to install this one for me. EVERYTHING worked properly after installation was complete, especially like the "soft-close" feature, where the opener slows down for the last few inches of travel, stopping with a soft close vs. a stop with a "bang". Also very much like the motion sensor on the wall remote, which turns on the light when you walk into the garage; not all openers have this feature. VERY quiet operation, even quieter than my previous belt-drive model. Camera video quality pretty decent, too.

Easy install and smooth functionality. Use the 2.4 band!
Easy to install. Much more quiet than my previous unit but also functions much faster. Love the ability to open/close remotely as well as viewing through the incorporated camera. Only flaw, the wall unit did not function and I had to purchase a different unit- but it easily connected without issue.

Might pass on this specific opener model.
Good company, long success history, but the remotes and also wall button on this one did not work at all other than to display amber light. Called the original supplier and they couldn't come up with a reason after the main initial potential fixes were ruled out. Thinking mainly if I did consider buying this one again i might hook up the remote electrical items to the opener FIRST and TEST it followed by assembling the travel bar and opener. All the best.

Great upgrade
I had to replace 3 garage door motors and was on the fence about how much “Tech” I wanted on a motor that I only needed to open/close a door. I bought these on a Black Friday deal so that pushed me over the fence. They work great, super quiet and great range on the garage door remotes. Installation was made easy using the QR code to download the installation manual/video so if you know how to turn a wrench it’s almost impossible to mess it up. The first motor took 40 mins to install while the third motor took 15 minutes. I was able to reuse the existing garage door sensors on 2 of the three doors without any issues. Now for the “Tech” review… The App acts like any other App, when it works it’s awesome, but when it doesn’t it is absolutely frustrating. In my humble opinion that’s just technology and I’ll say that since I installed these in November and it now is February, it’s been working for me 75 percent of the time. I look at it as a “plus” feature so it’s not a deal breaker but I didn’t buy these to “depend” on the app feature. All in all, they are a great motor. I’d definitely purchase again if I had to but only if they are on sale…

Tuve mala experiencia con este motor por varias razones. Primeramente, en la descripcion decia que era de 10 pies y venian solamente a 8 pies (2.44m) Ademas el brazo guia que viene es un tubular rectangular lo cual hace que se doble o pandee al momento de meterle carga. Ese movimiento de pandeo, hace que se descalibren los limites programados. La app es facil de usar, pero si quieres acceder a la camara, tienes que pagar una anualidad. No admite cambiar controles a otra marca o programar el que venia incluido en mi camioneta.
