All of my friends know me as the person to come to for recommendations and I was excited about this product until about 3 months after using it. It just stopped working!! I went through 2 packs of new batteries rationalizing that it "might be the batteries" but it is definitely the unit! I have exchanged it twice and had to pay shipping to do that. I couldn't be any more disappointed with this purchase. And since it was my first one from Overstock. I am a little leery of purchasing anything else.
