I order 1000 roll, and I received a 1000 roll. Wire was easy to work and slid through my bare hand without a scratch. My railing included a 93 run. Originally, I planned to make it 3 separate runs of approximately 30 each, but I changed to one 93 run. Seemed to tighten fine, but only time and temperature variance will tell how much more, if any, I will need to tighten. I have 1-2 I can tighten if needed. More than that I_l have a problem and will write another review. I_ not sure what is meant by _heerness so I don_ know about it.
