I'm giving this company five stars because of one employee, Trish. She goes above and beyond any customer service representative I've ever worked with. She is the reason I have stayed with this company for so long. She is knowledgeable and ensures the customer is satisfied. Sting alarm is reliable when an alarm goes off and always calls right away. My only complaint was the lack of service when something malfunctions, however, recently the company and especially Trish have been great.
