The unit is light weight. Almost flimsy. Put the enclosed roll of bag material in and proceeded to make some bags. The cutter takes a few slides back and forth to get it to start the cut. If you don't hold the hold down bar, which is very flimsy and I wager the first thing to break, down tight the cutter just pushes the material crooked and won't cut it without sliding it back and forth a couple times. Had an old vacusealer with a cutter built in that cut effortlessly.
