★☆☆☆☆
Absolutely Worthless
This device flat out doesn’t work. Everything shows as a diamond. My diamonds are diamonds. My gold band is a diamond. My keys are diamond. Screwdrivers, corkscrews, my mailbox. Everything rings up in the red as a diamond. I’ve read the instructions, re-read them, calibrated it, and still — everything’s a diamond. Total junk.
