I like the larger area to test on

Works great for gold testing

This definitely a professional stone for testing metals. Good testing surface with non-slip bottom for easy use. Glad I got it.

Does exactly as we hoped.Good value, Good product.

Just the regular stone. After 2020 one company makes them all.

The best, lead with integrity and honor.

this testing stone does not work well it also cannot be buffed flatter to make it work better. The surface is too gritty. You cannot lay down a smooth or dense layer of metal to do your testing. I’m returning mine. It’s absolutely useless. Please see the video comparing my smaller stone that works infinitely better. I still want another stone that’s larger because I do a lot of testing, but I will find one with a better surface than this listing has to offer.

It looked ok, i am sure it will be fine, buy I have not opened it up yet

Well a some what very expensive item in comparison to other sellers .I assume d this would include acids for doing test s,after trying to find out via Rufus .I was unable to get info I wanted .the advert info is a bit confusing .no instructions as advised on the item itself were included.abd any acids have to be ordered separately ,and a hefty delivery charge on the top of the purchase .I'm sure the other less expensive stone will do the job.sirley they all do the same.some acids don't guarantee English instructions???? So I'm not too happy so far.but will update of any thing else I've found .good luck ???

Bad product
