I came in yesterday to have my Xbox 360 looked at as I thought it was making a whining noise louder than it should. The shop took the time to hook my Xbox up and test it. They said it was the hard drive spinning and not the fan as I thought, and they noise seemed reasonable.
Not only did they save me the time of sending my Xbox back to Microsoft, they did this check without cost.
I surely will be back when something does go wrong.
Thank you.
