Title: Be Careful
Review: We used the test kit to identify a small pile of unmarked gold, sold it on eBay and the customer was satisfied. Next three lots of scrap didn't come out so well. Despite carefully following the (somewhat minimal) instructions that came with the kit, and repeating the test several times, the eBay buyers informed us that we had made a mistake and they wanted their money refunded (naturally we waited until we received the returns and made absolutely certain the buyers had returned the exact same items sold.) Besides the obvious "all that glitters is not gold", we learned that it takes lots of practice and possibly even expert instruction to test gold.
