This machine works very well on pretty much anything you put in there. I have used it back to back to back for hours sometimes sealing food that I freeze dried and never had a machine related issue with it. Sometimes with fine powdered stuff you must clean the plastic bag VERY good because the dust can cause the seal to fail over time, but that's not a machine fault, that's just a face of canning. It's very easy to use and works great on liquids too. I just wish the inner shape was a bit deeper so it could hold mason jars in it so that you can vac seal them as well, but it does good at what it does.
