Negative Positive
Title: Good Service
Review: Came quickly, no problems at all. Very competitive price. Note that the Chamberlain and LiftMaster versions of this switch are interchangable. I have both. Note that the Chamberlain version has better illumination on the button (the whole square lights up), while the LiftMaster only has a small LED in the center. However, I didn't think this was worth an extra $10!
