The red ring of death appeared mid last week. I have had the unit about 5 years with a lot of stored gaming and could not imagine losing the info.
The repair was smooth and detailed. I have little patience hence my wife performing the opertion. The kit and instructions allowed her, an absolute novice to perform a relatively difficult electronics repair with little or no snags. The repair was successful and once again I am up and gaming. Although the process did take a few hours, it was primarily because she took it slow and deliberate.
Please remember the Xbox 360 opening tool... she spent several minutes using a small screwdriver to open the rear of the case before recognizing it's significance and importance.
