Customer-rating aggregates are mixed: five-star ratings make up the largest share, but one-star ratings are also a substantial part of the distribution. With no written feedback supplied, the ratings do not establish why users were satisfied or dissatisfied. For buyers considering a motion-triggered garden deterrent, they are not evidence that the claimed sensor range or animal-deterrent effect will be achieved in a particular garden.
