Title: Did anyone at Chamberlain ever test these ?
Review: I bought the pickup unit with sensor and an extra sensor in one shot. This device gets confused all the time with two sensors, and sometimes the signal does not get picked up at all, from even a few feet away. I've never had a wireless device that was so useless. I think I'll just buy a few roller switches and hardwire a doorbell/LED to them.Just too bad I waited so long to test this out before I found out how they worked.
Is this product review negative?
