After a few minutes of setup, I was labeling my jars without a hitch. The included instructions left a bit to be desired, but it was easy enough to figure out the assembly, alignment, and positioning. The machine is well-built and very solid.I was concerned that the weight of a 32-ounce HDPE wide-mouth jar wouldn't be sufficient for the label to adhere properly, but with proper roller setup to position it correctly, it's just fine.
