I had access to a 901 machine at work and had been using it for shipping/packing my restorations and repairs for the past nine years. New managers have made it more difficult to access. It was a slight pain in the rear to use, only in getting the units to my work and then to the shipping/receiving department. So, I bought one on eBay from a gal who had salvaged one from a Pack-n-Ship store. I had user maintenance experience in keeping the system operating and would inform the company when new material was needed. I never thought one day I would own one. Well, there's a ton of things to know about these units. First: Sealed Air sells the new systems and only services the ones they sell. To become a customer, you must buy a system from them. This makes it hard to get parts and access to technical info for the packing system. It is a well built system and the one I've used never required a service tech, that I know of (Some of the tech support is over the phone). I'm an aircraft tech by trade and have most of the knowledge needed to keep this machine going but nothing beats the AK Audio site for access to audio information (Right!). Maybe there is one for these units? I ended up buying a second unit for parts. That one was actually in better shape than the first one, and I was able to make one good unit out of two. Plus, I gained a few new cubes of material to boot! I was hoping others might share their experiences in maintaining these wonderful packing systems. There's a lot of info that I could speak of but wondered if anyone wants to share their knowledge of these packing systems? Some other thoughts: The material used in this system is expensive but the economy is in the scale of it's need. If you only ship 50 heavy, fragile items out a year, it's barely worth it . I got the equipment and material cheap. I have the space to handle it and hope others in my audio community will need the service.
