I am a very handy guy and have worked on cars and houses most of my adolescent and adult life so I was not afraid to tackle putting up a new garage door opener when my old one finally died. I did my research, looked for one that work work in a modern, automated home, and settled on the Beam BU800 Centurion. I picked the model because of its features, motor sized, linkage type, price, and customer reviews. This one checked all the boxes. I ordered it and promptly let it sit in the box in my garage for the next six months! LOL! 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!

As a homeowner who has never installed a garage door opener I was a bit intimidated taking this on. It is not perfect but it is pretty close. I installed it alone, without help and with one exception the manual is outstanding. I have two, well maybe three, complaints but they are minor. On my first attempt to install I followed the instructions to a tee. There was a page explaining how to install the chain followed by a page explaining how to install the belt. When I got to the chain install I discovered I had no chain. Believing the chain was for the gear assembly and the belt connected to it I called support to discuss the missing part. Support did call back but argued with me saying to return the product to the seller (Amazon) rather than providing a fix. Only after telling them it was assembled and return was not an option did the technician mention that the units are chain or belt driven. There is no unit with a chain and a belt so he then said to skip the page about chain install. Didn’t care much for his attitude. This leads to complaint number three. If you send a manual covering multiple units and some steps are not relevant, say that. The page with “chain installation” should have a huge notation saying “if your unit is belt driven skip this step”. Probably not needed for someone who installs openers everyday but for a homeowner who does this once a decade it would help. My additional complaint is also minor. The clips for installing the new wiring are garbage. Too small to use unless you have the hands of a child. I bought a low voltage wire stapler after getting frustrated with the tiny clips and turned a three hour frustrating job into a fifteen minute simple task. Don’t wast your time with these wire clips. BeemUp, don’t send this junk. Recommend a stapler for low voltage wire or include one as an option ( Amazon does offer them) Overall this is an excellent product. Install is easy for one person (if you understand the error in the instructions and have the proper stapler). The average homeowner can complete this in a couple hours. It is smooth, quiet and programs easily. Haven’t tried to connect it to the factory garage door openers in my car but I expect it should be easy or tech support can provide an answer if the tech comprehends what you are saying.
