First use one of them came apart and ruined it. The smallest one in the pack just blew apart. 3/4" to 2" just wanted everyone to know this company reached out to me. They are willing to replace the one that flew apart. And maybe it was my fault. I'm not sure, but anyway, they made it right. And for reaching out and making it right, they deserve an A+

a must have for every toolbox

Abrasive pads had uneven surfaces so I had to cut the sticking edges off with a wire cutter. Still did the great job

They’re all right, they worked fine. Did what they were supposed to do.

not awful, but not great. i wouldnt use it everyday but good if ya need it in a pinch

What a nice set. They worked great.

Worked as expected and case was a nice way to keep from damaging stones.

Broke instantly first use. The metal holders are thin metal and weak. It twisted and the stone broke off. Returned
