I have been using these ceramic mouse glides for over a year. I bought them to try and I am sold on them. They are easy to install, and very durable. I use a cloth mousepad, they glide effortlessly around. At first I thought they might lift my mouse to high so when my old Teflon guides wore out, I removed them and replaced them with ceramics. I have had 2 new mice since then and now I just install on top of the factory ones. No problem. here's the link to the website https://www.lexip.co/en/products/Mo42 here's the link to the Amazon page https://www.amazon.com/Ceramic-mouse.../dp/B07MW5XJ8G right now they are on sale 50% off =9.99.
