If there was a tornado, we all could find out from the news. We have not seen any things from the news on the weekend. The company said that was due to the wind. As you know the wind is much stronger in the winter. We should expect the fences can last at least 10 years. I think that is reasonable. From the pictures, I can not image that can stand for 10 years.
The company tried to cover up itself. It said: "cost damage by nature will not cover." I asked what warranties was for. Is it to protect the company or the consumers. You can say all the problems for the fences cost by Gravity. So you should tell us there is no warranties at the beginning.
I understood the another said he/she is lucky. However, we felt the same thing before until they fell down.
Anyway, I am here just try to remind all the friends who are looking for building fences. Please spend a little more time to shop around before you make any decision.
