I have used this type of product many,many times.  It is almost invisible, which can be good or bad.  We have had a few birds and squirrels run into it, sometimes getting caught, and sometimes bouncing off (seriously!).  It is not as strong as a metal fence, of course and if you run into it while walking past with a board or something it's going to rip.  Still, at six feet tall, it provided an adequate fence for my garden that kept out the deer. I don't think it would keep the local bear out if he was determined enough, but then you never know.  It also worked as a one-use pea vine support.  It ripped when I pulled the weeds I should never have allowed to get that big.  As an affordable, easy-to-use way to fence things, it's very good.  i will be using more this week, because my daughter's puppy has decided to use the soft dirt near my rhubarb plants to dig to China.  He is easily discouraged, so I think four posts and a length of this netting will do the job.  The affordable price certainly helped, as we have been moving into a new house (to us) and there are a lot of expenses.
