If the reviews are all over the place it is a sign of a product with some fake reviews being posted. You will have outliers, crazy people, sometimes just too stupid to use the product according to directions, sometimes just azzholes upset about their lives so they post a negative review. But if it is over 5%, look out. A product ought to have reviews that group at one end of the range or the other, so if they are all over the place you likely have a company using the paid review companies that send emails to businesses all the time. Cheap to do, a few bucks or less if you buy them in quantity. Some are third world companies grinding out dozens of reviews per day per worker. On others the review company advertises for consumers, they set up the deal, the customer buys the product, and in exchange for their money back they place a glowing review.
As for a light deterring predators, not likely gonna work. Lots of people have yard lights in the country and city so the critters just get used to the artificial lights. Best to just invest in a sold coop with hardware cloth stapled over the outside and if you re in bear country go ahead and invest in the electric fencing. Not chicken wire by itself, maybe over welded wire fencing, and if you have coons visiting watch how you latch the door as coons are very intelligent and can easily figure out most latches. A lock is the safest.
