1) More complicated then it sounded
2) More work then acid testing
3) more costly then acid testing due to gel
4) keeping it as backup tester

This tester is not reliable. It gives false positives and cannot distinguish gold-filled from solid karat gold. It gave a reading of 721 on a US gold eagle coin and a reading of 945 on a sterling ring electroplated in 18k gold. Out of three readings on the same piece of plated Chinese fake "10k white gold" it read 435, then 509, then 415. When I put 18k testing solution on the piece, it started to cook out, with yellow smoke and green bubbles, after the GT 3000 tester had given three readings within range of low karat gold.

It also gives false negatives and low readings on known high grade gold coins and bullion bars.

If I had known what an unreliable piece of junk this thing is, I would never have bought it. Too bad that one star is the lowest rating available, or I would have given it a negative 3 stars.
