Apparently there was a change in the packing material guide after 2014.
If you received one of these newer units, you will notice that the included unpacking and packing guide is dated 2015.
Noting that the online supposedly latest guide is dated 2014.

The later version is much better protected albeit a bit larger.

Anyone near Oregon need a CubePro pallet and box set? 50% off the retail price! And assured up to date!
...and I'm not shipping it! Located PDX West Side.

This does, of course, let you ask any potential CubePro seller what date their manual was printed.

I guess it doesn't hurt to know the date on the included cartridges if the CubePro is new.
I have a March'15 and a July'15 date on my included cartridges, red and white ABS respectively.
