Here is a review left by a customer on a product. Would you say he was satisfied or dissatisfied?
Title: Works well for approx. 4 yrs then need to replace.
Review: Pros: The lamp's photoelectric sensor correctly determines dusk even under a roof or awning. The lamp's motion detection works well on distant and close moving objects. The multiple appearance configurations is appreciated.Con: Now on my fourth unit, their motion detection system wears out approx. four years after purchase. They have all been under roofs.Still worth the price and re-installation effort.
