Before I could secure the base, a few rabits had gotten into the garden.  As I came out of the house, they made a run for it and I actually watched as one hit the net, was paused for a split second and then kept going.  the other rabbit just ran right through. In both cases, there were nice, rabbit-sized holes in the bottom of of the fencing.  Great concept, easy install (I pounded 10' lenghts of 1/2" conduit in every 10' or so) but buy something with more strength.
