New vs. refurbished text terminals

The advantages of buying new, factory-built text terminals outweigh the marginal savings of buying refurbished text terminals.

First, a new Boundless terminal comes with a three-year warranty. While that's longer than most refurbishers offer, it's not even the most important thing. The main benefit is that you can expect your new terminal to last for many more years after the warranty ends than a refurb would.  Why? A refurbished text terminal will be many years old – with many of its components nearing the end of their expected lifetime – before it even reaches you. With a new terminal, you get all new components – and maximum expected lifetime for your investment.

Second, with a new Boundless terminal you can get the exact configuration you need. Choose from our extensive line of systems and options. For most models we will customize the hardware and software, add your logo or splash screen, and more.

Boundless text terminals are manufactured at our ISO 9001:2008 certified factory in Western New York. They are built to order at the quantity and delivery schedule you need. Call us today!
