I only purchased this item because I had to have it for a class in collage. But what I recieved was a dinged up hunk of junk with a screen that has a line threw it that makes it very hard to read the anwsers to the calculation you put into it. No good, just junk. I could have got a nock off brand from Wallgreens for $14 and it would have dune the job. So to sum up how I feel about this Is I paided to much for a abused and broken calculator.
