Review on 🚪 Chamberlain B550 Smart Garage Door Opener - myQ Smartphone Controlled - Ultra Quiet & Strong Belt Drive with Powerful Lifting Capability - Includes Wireless Keypad - Blue by Robert Hoge

Instructions are small, especially with regard to belt tensioners, bogie connection and travel adjustment. Worse, the parts were of poor quality. Now I have to wait almost 2 weeks for replacement parts and HOPE they send the correct ones as the defective parts are not the ones listed individually on the parts pages. And technical support. Although they somehow figured it out in the end, it took ages and required access to a manual they didn't include, as well as videos they don't host. Worse, the videos they sent were for a silent chain drive, which has very little in common with a smart belt drive. You have to pay a subscription fee to really integrate this into your smart home! Further processing. after AMAZON replaced the faulty parts (for free, thanks Revain) and I installed the belt tensioner correctly (btw, DO NOT follow the instructions on this one! First make sure the bolt can actually go through the hole in the carriage and I my slide. I had to file it for more than 30 minutes before it happened with the replacement. After you connect the other end to the chain link to the belt and connect the other end of the belt past the pulley, continue, pull On the other side, tighten the nut/spring combination until the bolt protrudes at least 1/2 inch past the square nut. Then, while holding the nut, use a flathead screwdriver to loosen the washer so the spring snaps into place.) Like so . after it works. the wall unit is out of order. So the remote controls open the door perfectly, as do the controls directly on the opener, but the wall unit also needs replacing although it worked fine before I waited 9 days for a part (didn't call Revain straight away.) It's worth noting that Chamberlain's parts haven't arrived yet.
