When we ship/hand your equipment back there are a few things handed back in the bag/box. We attach your itemized invoice to your service ticket. The invoice includes a quantitative breakdown including the price for service by the technicians, all the service kits, and any extra parts that were needed for service. It also includes any notes taken by the technician regarding the stage of the regulator, anything noticed during servicing, or anything that had to be replaced for proper function. We also attach a ‘used parts’ bag to each regulator set with all of the items that had been replaced during service.
