Cosmos Replacement Mouse Feet Pads Compatible with MX Master (1st Gen) and Also for MX Master 2S 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!

Damaged the originals when I took the mouse apart to fix a stuck app switcher butto (thumb). Originals were dirty anyways, now it's nice and clean. Make sure you remove the plastic protective film on them when you replace.

I got these to replace the original pads which were peeling and getting caught on cloth surfaces. I decided to get these as I assumed that they were also made from PTFE or the same smooth gliding material.After removing the original pads using a plastic scraping tool with some Goo Gone to remove the residue, it was time to install. I decided to test the mouse without pads and was surprisingly smooth on any surface and I almost decided not to install the pads at that point, I decided to install them.The pads exactly fit the shapes of my MX Master 1st gen and adhered well. However, when I tested the mouse over a countertop, desk mat, and mouse pad, the mouse did not glide as effortlessly and almost seemed to grip the surface which made them completely useless. At this point I regretted even buying them and going through the trouble of even switching the pads.HOWEVER! I was shocked to see a thin film starting to peel off. At that point I realized that this was probably a protective film so after removal on all the pads, the pads worked just fine and almost, just almost, as smooth as the originals.

Got these for my MX Master 3. They're not technically the same size as the stock Logitech pads, but I cut them down a bit and they work just as well. Only thing is there is a thin, clear plastic coating on the top of these pads (the non-adhesive side). After a few days, I thought these pads were wearing out. But it turns out I just had to remove the protective coating and everything was smooth afterwards.

After I [thoroughly] cleaned my MX Master (OG) it stopped working. I found that a common problem is that the "gesture button" gets stuck and needs to be loosened. To do so, I had to remove the to larger pads to get to 4 of the 6 screws. Of course, the old pads could not be reused and I needed replacements (the two small ones were unaffected though). I found these and ordered them right away. They came extremely quickly and were neatly packaged (although the decor on the zipper bag look like mold haha).The biggest challenge was to clean out all of the sticky residue from the original pads but some good rubbing with mineral spirits followed by degreasing with alcohol worked well. The pad attached nicely and seem to stick well. As others noted, there is a protective clear film on the pads that should be removed before use. My mouse is fully functional again and I am sure the pads will hold up just as much as the original ones.

Title says it all. These adhered well and fit just like the original pads. They made the mouse skate smoothly again just like the originals. I tried re-adhering the original pads, but that would not work - these worked like a charm. I also like that it comes with 2 sets, so I can do it again if need be. Overall fantastic product, well worth the 6 bucks if you have issues with your original pads.

After using the pads felt rough after a couple days. It looked like a scratch on the new pad, but when I rubbed it with my shirt sleeve, it created anothrt scratch and started rubbing off. My original pads lasted years, these didn’t last a week. Made of the wrong material.

I got this because I was doing a DIY project replacing the battery on my 1st generation MX Master wireless mouse. Fits and it was so easy to install. Took seconds, and the adhesive sticking holds well. Been over 2 weeks, and no issues so far.
