When I finally got around to putting it up, it was easy to put together and the instructions were pretty easy to follow. I was able to use my old garage door openers ceiling bracket, garage door bracket, and track bracket over the garage door. I had the new Beam BU800 up in less than an hour. I followed the programming guide and set both my upper and lower limits and the automatic force programming worked just fine.
I then did a test run and the garage door opened smoothly and with out issue. However, when I went to close the garage door, it would only move it about three inches and then stop and sound a series of warning beeps (20 to be exact). I tried it again with the same results. I reprogrammed it and tried again, same results. At this point, I decided to contact Beam Support. I quickly video the opening and attempted closing of the garage door, attached it to an e-mail and set it Beam support on a Sunday night around 8:30 PM. The next morning I had a phone call from Beam support and I walked the engineer through the issue. They had me check the beams, then they had me over ride the automatically learned force setting to apply more downward force. This did not fix the issue. They asked that I make sure that there was no binding with the rollers, they were properly oiled, and that the tension on the torsion spring was set right. Instead of me messing with the torsion spring (for those who don't know, they are very dangers and can severely hurt you if you are not careful) I called my local garage door company (who installed the garage door when we build the house) and they came out made some adjustments (because it was a little stiff) and even helped me "troubleshoot" the opener. They agreed that it had to be something with the garage door opener itself.
I contact Beam Support again and this time they said they were shipping me out a new logic board to replace the one in the BU800. It got here yesterday and before it had even been delivered, Beam support reached out and asked if I had received the part and if I needed their help to install it. I did not have the part yet and did not know it would be delivered later in the day. When it did come, I e-mail Beam Support to let them know it was here and asked them how they wanted me to replace it. They sent detailed instruction on what to do. It took me about 15 minutes to remove the old logic board and replace it with the new logic board.
After it was replaced, and before I put the engine housing back together, I programmed the up and down limits and the force and ran a test cycle. VIOLA! It worked just like I expected it to!!! I ran probably close to 10 additional cycles just to make sure it did not have any issues. It worked every time just like it should.
I know may of you will read this and say "it should have work out of the box" and while that may be true, you never know how something was handled at the warehouse or in shipping so I cannot fault them for it not working. What I can do is praise them for having fantastic customer service and never ignoring my requests for help. They were Johnny-On-The-Spot and helped me get it working as advertised!
The product is much quieter than my old chain driven open, works with my home automation system and has all the features I am looking for. I would highly recommend this product and this company to anyone who is looking for a good, powerful, quiet, product that comes from a company that will stand behind its product!
And no, I was not paid to write this nor did I get a "sample" product to review. I purchased this with my own hard earned money and I am will say it was worth every penny!
They're quiet, consistent and the lighting is great! The motion sensor works well - I had one incident where one didn't turn off - I unplugged the unit and plugged it back in and it's been fine since that one time.
What I don't like? The garage door "Smart Controller" - you program it using their app and it sends light pulses to program the unit. This programming is wildly unreliable. I programmed one unit successfully after several attempts (more than 5) - following the directions in excruciating detail. The second unit refuses to pair at all - I've tried more than 10x and get the same blinking red light of failure. I have VERY strong WiFi in my house and I'm using the recommended 2.4Ghz band.
I'm going to buy another company's controller and toss this brand's controller in the electronics recycling bin.

Se puede abrir con una aplicación desde el celular y los controles de puerta que se programan muy fácil . No lo he probado con Alexa con lo que se supone que también funciona.
De los que e tenido este es el mejor .
