CosmosReplacement Mouse Feet Pads Compatible with MX Master (1st Gen) and Also for MX Master 2S Gaming Mouse, 2 Sets

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.

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!

After 4+ years of daily use, I recently did a deep clean on my MX Master. I had not intended to replace the four feet on the mouse, they were pretty beat-up from all the use and didn't reinstall cleanly after being removed (the factory adhesive is definitely a single-use product). This seemed like a good option to try: I figured if I failed the first attempt at installation, I could always pull from the second set.Before attempting installation, surface prep is CRITICAL. Use a microfiber cloth (cotton will leave lint behind) and high-proof isopropyl alcohol. I put the alcohol on the microfiber cloth and laid it on top of the remaining adhesive to "soak". After a minute of soaking, I moved to a clean area of the microfiber cloth, applied more alcohol, and gently scrubbed it away. I repeated this process until the bottom of the mouse was spotless and free of any adhesive reside.Next, I unpeeled each of the feet from the adhesive backing, lined up the "flat" edge of the pad to the appropriate area on the mouse, and applied the feet. In essence: laying the pads "middle-out". This helped me center the feet pads in each of the cut-outs. While the front, left, and back pads fit perfectly, I did notice that the right (oval-shaped) pad on mine appeared to be cut ever so slightly too long - so it does not fit perfectly in the cutout. After taking the attached photo, I trimmed off a sliver of the pad. The final step of this process is to peel off a very thin, translucent protective plastic film from the non-adhesive side of the pads. If you fail to complete this step, you may find that the mouse will not glide nicely.The performance improvement after installation was immediately noticeable. The mouse glides smoothly across my wooden desk, aluminum mouse-pad, and fabric mouse-pad. The adhesive appears to be of equal quality to the factory pads: there is no lifting or adhesive leak from the sides.In short, this is the way to go. I would have given five stars if the oval-shaped pad on the right side of the mouse was cut as accurately as the other three pads.

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.

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.

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.

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.

These work really well. I was looking for a new mouse because mine kept catching the thread on my mouse pad. I changed these out quickly and it was easy to put on.It was a little tough to move the mouse around at first then realized there was a plastic film on them that you take off and it glides like a champ.
