This is a very simple designed machine.
For the cost the machine is great. I've packaged and repackage many items with it as well as tested wet and dry items alike with no issues.
It works with my old food saver bags as well as pouches and came with everything needed to get started. FYI it comes with NO pouches.
I understood the instructions just fine, but I've also seen a lot of videos as well as work with different types of machinery on the regular.
It does not come with an attachment for the chamber pots, but it seems like it could be easily modified to accommodate (would not suggest trying this during warranty period or without knowledge on the matter).
Packaging was excellent and arrived in time. Chamber is roughly 2.75" deep and comes with stainless steel filler plate. It can easily handle 12"x14" bags, which is large enough for me.
This is well worth the sub $400 that I paid for it. Next closest that I was interested in cost about $900 before shipping and taxes. The next model up had a 5" deep chamber, but fine with the sacrifice for now.
If you're on the fence, just get it. Don't paralyze yourself with research like I did initially.
