Cosmos Replacement Mouse Feet Pads for MX Master Gaming Mouse, 2 Sets

I started having problems with my Logitech MX Master 2S wheel getting stuck between ratchet and free-wheeling modes. After finding a video on how to disassemble the mouse, I looked for replacement PTFE pads since I knew I'd be destroying the original ones. Found these on Amazon and for the price, couldn't pass them up. Once I received them, I disassembled my mouse and tried to fix the wheel ratchet. Upon reassembly, the replacement pads were fit very well. They were slightly undersized, so they fit into the mouse's recesses nicely. Note - there is a protective film over the non-adhesive surface that you need to remove once the pads are installed! If you don't, the pads will still glide but not as smooth as the virgin surface! Thankfully there were two sets on each sheet. I found out quickly that the "fix" I implemented didn't really do anything. The mouse wheel ratchet was still sticking! Today, I performed another operation on the mouse and I believe I actually fixed the problem this time. Instead of pushing down on the plastic piece attached to the motor shaft I pulled it up so that it cannot now over-rotate and cause the ratchet to get stuck in an intermediate position. With that now fixed, I reassembled the mouse and used the second set of large pads to get me back up and running. Hopefully this fix will last more than a couple hours! I have two additional sheets in my cart right now ready to pull the trigger on another purchase once I find more things I can't live without. If you need to disassemble your MX Master 2S, you NEED to have a sheet of these on hand for when you put the mouse back together! The ONLY quibble I have is that when I removed the pads today, the PTFE layer separated and left the bottom adhesive layer in place. Thankfully, I could get my nail underneath it to get it loose and removed. The original pads came off as one piece, but did leave a small amount of residue that needed to be removed. Either way, these pads are a good investment to keep your mouse going!

Fit right and stay in place. Great replacement pad

Excellent - Perfect replicas/exact replacements for the MX Master

These replacement mouse feet fit my Logitech MX Master perfectly and were easy to install. Once installed, the mouse glided smoothly again and felt almost like new. The adhesive holds well, and getting two complete sets makes this an excellent value.

Saved my mouse, I had to repair them and I’m glad I found these didn’t need to use the old ones
