I bought it for rodent repellent purposes, specifically for blind mice. The instructions say that it will take 1-3 weeks to drive away the blind mouse. After three weeks, approaching the end of the month, the blind mouse continues to party... It's as if I didn't even use it. A friend who recommended it to us for snakes said it worked for her. So it probably does its job for snakes, but not for blind mice. Therefore, depending on why you need it, you decide whether to buy it or not. As for its durability in weather conditions, so far it has only experienced one satisfactory rain and had no problem continuing to work

Batteries are not included in the package, as for whether it does the job, we will see, for now we haven't seen anything, it was placed in the yard of the cottage
