Question: Can this be adjusted/reduced to only cover 1 acre etc?
Document: Then she told me that there are "holes" in the radio frequency and that my bedroom must fall into one of these holes. As for the right side of my house, I have a propane tank about 30 feet from the house and she said that this could be interfering with the radio frequency. As with the other reviewer, I had high hopes for this product. I live on a VERY flat, rectangular. 1.5 acre lot and I just can not get this to work for us.
We used this product for 1 month ok. Than the batteries started to not charge. Replaced them.Didn't last more than a month again.And they are not cheap.Than the unit started not shocking most of the time.Dogs came and went as they pleased. I would not buy this product.
This product will not operate located inside my home. The only way to get it to work was to locate it outside(under overhangs). With that, I can only obtain approx. 210 degree coverage. The balance was open for the dog to go as he pleases. I was going to put up a second one, outside as the other to cover the unguarded. This was not successful.
Product could be passible if it was 1/4 the price. For that price I expect perfection (just like I get from a similar wireless product now. )The batteries don't even last the whole day. I find myself swapping out batteries to be recharged every 4-5 hours. Signal gets constantly lost and there is an annoying beeping sound when the battery gets to about 1/3 dead - can't get rid of the beep - there should be an option to mute it.
We also have tried repeatedly to make this work using many different locations. We called the company  several times and they all say that there is interference so there are places that it will not cover. The Station goes off even when the collar is next to it. The receiver is not accurate so that in one spot where we set the perimeter one day it will go off 10 ft before the flag. The next time it will not go off until 25ft past the flag.

Station goes off when the collar is off the dog and within 10ft of the base station.

Easy set up- it took all of 20 minutes for my wife and I to have it fully functional. Just make sure you are not setting it up near the fridge, car, TV, swingset, etc. as it will interfere with the WiFi capabilities.The only one not impressed with it is our 11 month old English Springer Spaniel!I rate this product 5 stars wholeheartedly!
there are some glitches but works well for what we needed - has had to be reset numerous times but flexibility of distance and warning system and stimulation system make it a positive
You have to change the batteries once a week. Now it freezes up and we cannot even get the thing to register our dog when she is right next to it. The only saving grace in all of this is our dog actually stays near our house. Otherwise, I would have pulled an "office space" on it weeks ago. I was thinking of selling it on ebay, but I would not wish this product on ANYONE!
We tested this and it did not work (not even within a 10% error margin as discussed on the company's web site). This was going to be a nice feature, but again the product failed.Hope this helps convince you to look elsewhere for a dog containment system.Todd
