  • "NTI’s products are fantastic, but their customer service is even better. In 2007, I purchased an ST-C5KVMA-300 KVM extender that allows me to access my main PC from a monitor, keyboard and mouse over 120 feet away. NTI sold the product at a terrific price, installation was easy and effortless, and the device has worked flawlessly for over seven years. When a recent power outage appeared to have damaged one component of the system, Phyllis of NTI’s customer service department was simply fabulous. She was able to locate my old order, identify the specific model that I had, and obtain prices for replacing either an individual component or the entire system (and I was very pleasantly surprised to learn that the cost of the entire system had only increased by less than 5% since my original purchase seven years ago)."

    The actual problem was in my outlet and not NTI’s device (NTI’s products are bulletproof), so I didn’t actually need to replace any component. However, Phyllis and NTI have my heartiest thanks for helping me understand my options, and for being willing to go the extra mile for a customer.

    Hats off to NTI and Phyllis for keeping me very happy with NTI and NTI’s products for many years. They are definitely my “go-to” vendor for KVM equipment. Out of five stars, NTI gets five for their equipment, and six for Phyllis!”

  • "I just wanted to drop you a note about how my install using your product went. The whole installation took practically no time at all and most of that was running the cat5 cable through conduit. I think this product (ST-C5KVM-300) is fantastic and the ease of use is just what I needed. I'm looking forward to more similar experiences."
