What do you think of this? (cat product)

I found info on this at the vet's office. Has anyone used it? It looks like a great way to keep cats safe while they are outside. Click to see what seems like a cool cat fence

I ordered the video and a sample piece of the fencing. From what I have read about it,it does sound like it is a very secure fence. Its pricey.. I need at least 3 of them for the area that I want covered. I am trying to convince hubby to part with the money come spring to get them. Crosses fingers and hopes he says ok!

Oooh! I've seen that before. I forgot about it. It looks nice!
