Review on 🔍 Set of 12 Soft Cutting Board Rubber Feet - Stainless Steel Screws Included (0.25"H x 0.687"W) - Soft, Non Slip, Non Marking, Anti-Skid, BPA Free - Made in USA - Perfect Grips for Furniture, Electronics, and Appliances! by Antoine Dean

Just a little tip. The included screws OR rivets (which I used) stick out too high and when other equipment is placed on top of the preamp, tuner, switch, air conditioner or whatever, the screws can damage the top of the underlying AV unit casing scratch. Not good. Solution; Take out the metal insert, hold it with pliers and file down a few millimeters of the - very soft - metal, THEN place it on the device. Definitely keeps things in place, COULD be a bit stickier but applying some silicone lube fixed it for me. I liked the product so much that I bought another set.
