About 10 years ago, I had a wired system from Invisible fence that was professionally installed and worked great.  Now I am in another house and my dog is 12 years old.  He does not have long to live, so I thought I would get a wireless system, and I was encouraged by the positive reviews.

Unfortunately,  the problem is that the receiver on the collar activates at wildly different distances from the transmitter each time.  These activation distances can be up to thirty feet different each time.  This makes it virtually impossible to figure out where to put the flags.  If you do stake out a position and put the flags down, when it comes time to train the dog, you will be unable to tell if the collar is activating because the tone is so high-pitched and the light does not flash.  The result is that the dog has no idea what you are trying to do, because he may or may not hear a beeping.  We both ended up very confused and frustrated.

I called tech support, and they told me to move the transmitter away from any metal objects, but this did not fix the problem.

Invisible Fence and PetSafe are distinct companies that are both owned by Radio Systems Corp.  I recommend that you call Invisible Fence.  It will cost more, but it is the right thing to do.

Update 1.5 years later:  OK, so don't get me wrong.  I returned this product over a year ago.  In that time, my dog died, I installed a real Invisible fence for about $1,300, I got a new dog, and I upgraded to the Boundary Plus Invisible Fence, which is an $1,800 product.  The reason for my update is that I was speaking with the installer recently when I upgraded to Boundary Plus, and we spoke about this Wireless Pet Containment System.  I told him that I thought it was a terrible product, and that Radio Systems Corp should stop selling it because of all the problems I experienced.  He said that I didn't even hit the main problem with this product.

If you have a power failure in your house, the pet containment system stops putting out a range signal.  The allowable range that your dog can be in shrinks to zero, and your dog automatically gets shocked, and this shock lasts forever.  So this product is actually quite dangerous.  I am now recommending that instead of spending $259 on this product,  call Invisible Fence and spend $1,800 for the Boundary Plus product.
