Used for horse pasture fence over the weekend. Ran through posts no problem and no knotting or catching. Does spring loose from the spool very easily due to being 1x19 strand, stay back as you cut the plastic wrap keeping it closed (learned the hard way on this one , it stings). The fence looks amazing and my horses can easily see it. Easily pulled tight across an acre just by using our hands, when paired with turnbuckles we got an great tension. So far a little stretching out, but super minimal.
