Well, yes it does seem to work, though with the usual limitations of electronic gold testers:

- it doesn't test through plating, you just file the item before testing
- it uses an acid contact fluid
- you will never know if the machine is rounding a reading up or down
- it's slow and laborious to use

and

- it doesn't read "9ct"

I do not recommend this model and I will not accept returns, so please be happy that you are getting a true 'bargain' and be aware that you get what you pay for.

Widely advertised, inexpensive, quick, portable, involves no acid (not even an acid contact fluid), instant results on a clear display.

The only snag is, we can't get it to work accurately. Sure, you get pretty colour lines across the test-paper, but they vary depending on the amount of pressure applied, the area that makes contact and the speed at which you 'draw' the item across the paper - in other words, the result bears little relation to what the gold actually is.

When you buy this and find that you CAN'T get sensible readings, you may NOT return it. If you buy this and find you that you CAN get sensible readings from this, please let us know how you did it.

As with all electronic gold testers, it does not test through plating.

This is an unusual item - it actually works quite well and the results are reasonably accurate. In fact the results are just about as accurate as acids, which is very good (though "just about as good as acids" does NOT mean the display is 100% accurate!).

As with all electronic gold testers, it does not test through plating, it uses acid (the contact gel is acid) and the acid stains the metal.

Since I specifically do NOT recommend this tester, I will NOT accept returns if you find you are 'not happy' or that the readings 'aren't consistent or accurate'.
