  • "I would like to thank you, Phyllis and NTI, for all that you do for JEOL. We have been purchasing the UNIMUX-USBV-4O-RS since 2006. We find the NTI USB KVM switch to be a very reliable product, and will continue to purchase. We've had very minimal problems with the units over the years, and I hardly ever have to contact you for an RMA for repair. It is nice to have a dependable product, but it is equally as important to us to have fantastic customer service. You have been a wonderful rep to our company. You are kind, friendly and eager to help. You are quick with email replies. That is something that is very important to our company that makes us keep coming back. Keep up the good work. I look forward to a long relationship with you and your company."

  • "I just wanted to drop you a line and let you know how much we love our new UNIMUX™ system. We are a multimedia graphics and presentation company and in the course of our work we end up with some unique needs. A recent show for A&E networks is a good example. We needed to have eight computer laptops running four different power point presentations that would be displayed on eight plasma screens and be in sync with each other. Your UNIMUX-USBV-8O USB KVM Switch did the job of controlling the eight laptops in perfect sync beautifully. We're happy to add the UNIMUX switch to our inventory and look forward to using it again. Thank you for all your assistance in helping me choose and purchase the unit."
