I had a question about the item that I purchased. Questions that the description did not address. Simple questions like does the item require batteries or electricity. Since the item allowed only a credit return it was important to me to find out if this purchase was going to work in my home. I posted the question on facebook and also on the site. I never got a response. Had to research the internet and other sites to find out information. Three hours later I got the answer to my question from another site.
