I sent them four calculators without reading any reviews, then saw the reviews and thought I had just lost $120, but then the paypal payment hit my account the next day for the exact amoutn I was quoted. I had a good experience - to anyone who didn't, did you try giving them a call? I called and asked about shipping before I sent anything in, but really to check if it was a scam, and they answered all my questions and seemed legit. So maybe I'm a rare case, but do give them a call if you have questions
