The process is less convoluted that you think.  The reason why we reqire the who kit to be returned is because they are registered as a kit.  This is very important becasue if we replaced just one unit and one of the other two failed you would not be able to replace it as the serial number would already show returned.  As for the process itself, well we have checks and balances in place to ensure products that are approved for RMA are truly RMAs.  The only way to do this is by troubleshooting.  Once it is complete we will have a supervisor to review the case and ensure nothing was missed.  At this point the RMA will either be approved and the customer can then create the replacement request or it will be reassigned to complete troubleshooting.  

This process can be completed on the same day, but depending on the time of day and call volume it might take 1 business day to complete.  I hope this clears this up a bit for you.

Best Regards
