I needed a replacement for the opener…
I needed a replacement for the opener outside my garage. I was concerned about getting the right part that would be able to be programmed with my Chamberlain unit. Actually, I don't know why there were so many negative reviews. They shipped as promised and it arrived at less than 3 days from when I ordered it. The instructions that came with the unit along with the instructions on the unit itself helped me to program it and it works fine. The unit even came with a battery. I was very pleased and gratified with the service this company gave.
