I bought a few from them but they had a limited supply at the time. Sent another query and have not heard back yet, so I figured I’d see if someone on here bought too many.
Yeah, I have been doing a few of my IGs. Nothing bad at all but, as has been commented on in the flattening threads, even fresh from the factory chips can have a little warpage. Hold a stack up to the light and if you can see light coming through, you have a little warp. Would like to be able to do more than 18 at a time though because with the heating up and then cooling down for several hours I can only do maybe 27 tops a day during the work week. I have 4 clamps so would like to knock out at least 80/day during the week and more on weekends.
