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.
