We run a ranch in Texas and agree that not only is it a helpful tool but a good branch of our marketing. We have about 18 both Primos and Cuddeback, primarily Primos and have had good luck with them. Not to say we have not had a bad one or 2 but for the most part they do the job required. All are equipped with ext. battery and solar panels. Trying to make as maintenance free as possible. If we upgrade we will more than likely stay with primos
