Query: Give it two years and then it breaks

I bought the same unit about 3 years ago in which it worked fine for about 2 years and then around year two my neighbor came running to me after going out to get some groceries for about 45 minutes with my dog in hand. The system failed even after reseting the unit it would work for about 1 week and then reset, after awhile it stopped working altogether. If you feel like spending money for something to work for 2 years and thats it then this is the product for you.
