Review on 📱 MANGZ Dispenser Expansion App by Ralph Gerry

It seemed to work pretty well for the first jar I looked at. I then cleaned it with Great Stuff Gun Cleaner as directed. I washed it until it became clear that everything seemed fine. Fast forward a few weeks, I throw in a new can, pull the trigger and... nothing. I fiddled with the valve, it ended up just starting to leak a bit, but completely unusable. I put down a can of detergent and tried to run it off just to see if I had bad suds but he did the same. So not only did it work after one can, but I spent another $15 can trying it and had to run to my warehouse at home to complete a weekend project.
