Title: Not Universal!
Product review: I bought these because my chamberlain Lifmaster Professional would no longer work in the direct sunshine. I read the reviews that these were great in direct sun applications and were universal. In the sun they're fine the beams worked great. Universal they are not. They are two wire just like my originals but wile they light up and work they don't communicate with my garage opener. I even tried wiring them both ways.On the issue of sensors working in direct sun, I bought new chamberlain sensors and they work just fine, just like the originals did 7 years ago. If your sensors don't work in direct sun they need to be adjusted or replaced.My biggest complaint about this product is they're universal claim. They need to have specific brands/models that they are truly compatible with.
