Review on AuRACLE AGT 1 Electronic Tester GemOro by Morgan Gilmore

I would like to return this item to Revain because it is not working. I've tried this several times over the last few months to no avail - I know the item is worth 14k but it registers as 10k. I've recalibrated it so many times that I'm so frustrated and I'm sorry I didn't read the reviews before making this expensive purchase. Can someone tell me how to get back? If I had bought from Best Buy or another brick-and-mortar store, I could easily return the defective item, but Revain won't let me figure out how. Seems like a buyer should beware if you haven't checked your item before the return window closes! This format forced me to give this product one star, but it didn't even deserve that.
