I have purchased a few systems through DVR Master. Each time I have made a transactions, had a warranty issue or just a general question, I have been extremely satisfied with the results. Service is prompt and prices are extremely competitive. In dealing with Leah (my contact for the company) she never disappoints and has always gone above and beyond to make sure we get the five star service experience. 10/10 I highly recommend!
