I cut holes in a countertop that I was painting www.amazon.com/Giani-Granite-FG-GI-SICILIAN-Countertops/dp/B0034IGVV2/ ref =sr_1_cc_1 ? s=aps&ie=UTF8&qid=1430339031&sr=1-1-catcorr&keywords=gianni+tabletop and it worked great. I even cut a hole in my regular desk to prevent the monitor wires from looping through the back. Then I cut one on the side (where the wall is) for the electrical wires. I love this product.
