We have been long-time clients of Invisible Fence of the S. Tier. The customer service is beyond excellent. They are prompt with any requests, explain all options and associated prices prior to the work, and they help with training your pets with adaption to the fencing. They have a wide variety of products. And, Brandi even sends our batteries at scheduled intervals, so I don’t even have to remember when to change them out. Invisible Fence of the S Tier will have life-long loyal clients with our pet family. We highly recommend this team of caring professionals!
