Why Buy From Black Box? Exceptional Value.

Exceptional Tech Support. Period.

Recognize any of these situations?

•You wait more than 30 minutes to get through to a vendor’s tech support.

•The so-called “tech” can’t help you or gives you the wrong answer.

•You don’t have a purchase order number and the tech refuses to help you.

•It’s 9 p.m. and you need help, but your vendor’s tech support line is closed.

According to a survey by Data Communications magazine, 90% of network managers surveyed say that getting the technical support they need is extremely important when choosing a vendor. But even though network managers pay anywhere from 10 to 20% of their overall purchase price for a basic service and support contract, the technical support and service they receive falls far short of their expectations—and certainly isn’t worth what they paid.

At Black Box, we guarantee the best value and the best support. You can even consult our Technical Support Experts before you buy if you need help selecting just the right component for your application.
