Question: I am going to buy either AGT3 or Tri electronicsGXL Next. which will you reccomend?
Document: I have worked with all of the electronic gold testers on the market and without a doubt, the GemOro AGT3 is the best, easiest to use and most accurate on the market. I highly recommend it to anyone in the gold buying business, it is AWESOME!
The gold tester is not accurate at all, you have to clean the pen after every test, you have to re calibrate many many times, and you have to use a file and ruin the jewelry when testing. it is a lot of money for something so inaccurate.
It tests plated gold as 18k.....the AC Plug doesn't stay in the Machine....the rechargeable Battery it comes with doesn't work on the machine....., you have to use a regular one.If you request a refund.....?The store will not accept returns if you opened or tested the item at all???? ?.So how are you suppose to know if it works if you can't try it.????
?If you request the return, a rude email comes back stating &#34; If the pen looks used or the AG3 looks like it has been used in any way your item will just be shipped back to you.
