I have got two invisible fences,one at my parents and one at home,i find the one at my parents is great,it is fitted around the garden fence and across the drive.The one i have at home is fitted in parts over open ground in places as i have fenced in two acres and i find that sometimes they will run through it as they dont know it is there,this is my fault as i have not taken them round on the lead to train them where the boundry is,but if i had a typical garden fenced all round just to stop them running flat out at it i wouild not hesitate to recommend it,My parents house had a five bar gate
