We were looking for a 1U 19" Rackmount LCD Keyboard console for our Flight Simulation System. KVMSwitchTech promptly responded to all our questions. We purchased several NRKD-KVM-19 Rackmount Console units from them and are very happy with the performance. Keep up the good work.
KVMSwitchTech helped us with a 1080p Rackmount Console with integrated 8 Port USB KVM Switch for our CNC Machines. The product works great and the staff is very friendly. I would recommend this Company.
