This is a brand new meter. I got it on a clearance and thought I would pass it on to my friends here. Here is the site of the product. http://www.radioshack.com/product/index.jsp?productId=2103668&cp=&sr=1&origkw=sound+level+meter+33-4050&kw=sound+level+meter+33-4050&parentPage=search It is still in original box with the manual. Asking $25.00 plus shipping, probably around 3-5 dollars. Thanks. Roly
