This is a great tool as long as everything has been hung with its use in mind. I thought it was garbage the first time I used it because the hangers left the corners gapped, I personally like to rotozip my corners, and when I do, this tool works as it’s intended and really speeds things up. I own a USG hopper and like it, but there’s a lot more work in cleaning it up and the bead is more likely to kink when it’s loaded with the weight of the mud. This applicator head can be pulled out on jobs big and small and it doesn’t break the bank. Give it a go for sure.
