I bought four tires around June 2010 in the camelback location in phoenix. Not sure if it was the tubes they used or the horrible roads in AZ, but I've had two tires replaced since then. Had a slow leak the second day of the trip, so once I had my spare put on, came to this location, was in and out within 30 minutes, and the tech were actually nice and joking around with each other. I don't know if it is just the Vegas vibe, but people out here are a heck of a lot nicer than the crapshack that is Phoenix. Great job guys!
