Testimonials
Discover what our customers say about our duplicators' reliability and performance.
I mainly use it to back up our critical systems, and I appreciate that it supports all kind of USB drives. The setup was really easy, and the speed is impressive. The only downside is that it gets a bit warm after extended use, but it's not a big deal.
