Thank you for participating in the Slingbox Answers Forum. We're happy to hear you'd like to join the Slingbox Technology! I understand your concerns when it comes to issues that could happen with our product. Slingbox is available 7 days a week, 365 days a year and we are more than happy to support our customers who may experience a problem. It's rare that we would have to replace the unit with this issue, so I strongly recommend purchasing a Slingbox for the football season.
Hope this Helps.
