Title: Not made to last more than a few weeks!!!
Review: When the product works, it's effective and the teaches the neighbors dogs not to bark. The problem is that this is the 2nd one I've owned and they have both stopped working after a very short amount of time. The first unit had a bad display after a month and without it you couldn't program when it comes on and shuts off. The second unit starts buzzing from the second I install the batteries so it's virtual useless to train the neighbors dogs since it's buzzing all the time. I think if the technology was made better, this would be a great product, but since it's not, it's a waste of money.I would not purchase this product again.
