I wanna see that wheel! Looks complex. Is it mechanical-coder? Optical? Or something new?

[@r1chard874]

Thanks! Mine fell from my desk on the floor. Sidebuttons didnt work anymore. Decided to try and open it. This video was very helpfull. Appeared to be a loose ribbon cable. Put it all back together and the MX Master 3 is performing as new again. Thanks!

[@el80ne]

My side buttons stopped working after replacing the battery. Do you remember if it was the inner ribbon cable at 2:48 that connects the side buttons that were loose?

[@gagank478]

My MX3 fell and it hasnt worked yet... Im debating on doing this and checking the inside! Thank you so much for showing how its done!!

[@yimingzhang2169]

The shell material of this mouse has a very short lifespan. I suspect that Logitech is deliberately reducing the product life. My mouse has only been used for a year and the shell material is already damaged and looks like it is melted.

[@Joshua-vm6xw]

I was going to buy a new one because of the same problem! The rubber was kinda sticky and awful :-( but recently I’ve found a replacement for the upper shell on aliexpress so i’m going to try and take apart mine and give it a new lease of life, fingers crossed!

[@jmtornetta]

Yes, I'm highly suspect of logitech after buying this mouse and will likely never buy another product from them. The design is fantastic, but the default switches on the 3s are very cheap and began failing after 1.1 year (1 year warranty). Logitech support gaslighted me for 2weeks with the typical nonsense until saying that they were unable to do anything but asked me to recycle the mouse because the company has "gone green" 😅. Luckily this video helped me dissemble the mouse and solder omicron switches onto the board, which solved the problem.

[@lmmillan]

I think the issue is cleaning the rubber cover with alcohol, that's what will make it sticky after a while. I've seen some people cleaning it with plain water.

[@HazewinDog]

The shell on mine is still flawless after almost 2 years, but my left click just stopped working properly... EDIT: for those wondering, I mostly dry clean, but if clean with liquid then it's with water, not alcohol.

[@LiTLflor]

That sucks. I've been using mine for 4 years now, and it is still in really good shape. Unfortunately there are many users reporting premature wear, than users such as myself. How many hours per day would you use your? I want to say I've probably put about 6000 hours on my mouse, mostly gaming.

[@nachodur]

My side buttons and side scroll wheel didn't work at all... After I watched your video I suspected that it could be the flex cable (the one that you disconnect right after you open the mouse). And I was right, that flex was disconnected! Now I connected it (and added some tape) and it works like a charm! THANKS FOR THE VIDEO!!!

[@gabrielcarrijo1846]

Mine just started presenting the same issue. Thanks for the tip!! By the way, how did you glue the bottom cushions back? I have to remove them in order to get to the screws and I'm afraid of damaging them.

[@DarrinLin]

@@gabrielcarrijo1846 they must be replaced. you can get replacement pads for cheap online.

[@TheJoao611]

@@gabrielcarrijo1846 I just removed them for a few minutes and put them back, they still got glue. Though they don't look as pretty as before

[@fritschdavid]

Thanks for the vid! It inspired me to fix my MX3 using parts from another one I had wrecked. It worked out great!

[@adamklase8547]

This mouse's left clicker has been known to stop working or malfunction for many buyers, and I think the main issue is the design heavily allows dust and particulates to enter and effect the buttons. So this is great for opening and cleaning every so often. Tho for 100 bucks you'd think someone would come up with a better design.

[@danielfletscher1416]

what switches do the side buttons use? are these omron as well? cuz theyre more silent than the typical omron switches

[@caiocsv]

Thanks! Waiting mx master 3s. Maybe there is a lot of people waiting to know about the switches Logitech used in

[@vladimirfasyura8191]

1:14 - torx 😢 .... on upgraded version, (3s) left and right silent buttons - 2-pin square buttons 😮 And double-clicking and no-clicking events But dont worry - you can replace it with silent huano brown switches (just cut 3rd pin)

[@krzysztofkupracz1697]

Hi, Thank you for this video - I was able to fix my non working ratchet with your manual. Cable did disconnect from ratchet motor.

[@carbidecore]

thanks, my mouse left button was dirty and this helped me

[@guaximim]

Thank you for the video. My mouse fell off and a screw got loose inside and got stuck in the wheel some days later. The video helped me opening the mouse and solve the problem.

[@brocksamson3282]

battery at 2:04

[@mattb9664]

Those click micro switch buttons looks like they'd be very easy to replace...unlike the G700 which is a bit of a project.

[@ahmadabdolsaheb]

Hi, if I model the mouse, mirror it, and 3d print it do you think I could use the electronics to make a left handed version?

[@agent_artifical]

actually yes!! did you try?

[@Cronofear]

Is it possible to bypass the battery and feed the mouse directly from the USB-c?

[@ptlinva]

Yes, my battery is dead and it works great connected via USB-c.

[@danieljoseph6404]

@@ptlinva How long have you had the mouse? Was the battery damaged anyhow?

[@sfh2050]

I only used CRC to clean the contact, all cables are properly connected but still red LED flashing. I think its effed.

[@PeakyBlindero]

can we change the battery to smaller one, so that there would be less weight ?

[@chunky_luva]

Unless I’m mistaken this video doesn’t show how to removed the side scroll mouse wheels and the other circuit boards from the inside of the upper shell.

[@edwardcastro5843]

I love everything about this mouse, except the fact that they put the button to switch devices on the bottom. And from your video, it doesn't look like that can really be changed.

[@javen2532]

Try M720. It’s a much better version of MX Master

[@winstonalf]

It is running on NRF52832 BLE SOC from Nordic Semiconductors.

[@5amJones69]

okay no how do I put it back together? hahah I can't manage to get the front clicking side of the mouse to sit correctly. Scared I'm going to throw it at a while in frustration

[@ChibiKeruchan]

2:04 may I know if that ruler on top 0-5-10 is in mm?

[@uiuxshoaib]

My question is: If a button stops working, like left mouse click (since its used the most) , so can it be replaced?

[@jonathandebrito2524]

same question

[@cheoksc2231]

From the video it shows no added metal piece for additional weight. Why the heck this mouse is so damn heavy.

[@cesarandres1288]

i think the wheight coms from the sheer size of the mouse and fro the two metal scroll wheels that it has

[@lenanaH]

If you removed the battery completely and plugged in direct, would the mouse still work? Are you able to verify? Thanks in advance

[@Fletscherrrr]

gotta love that logitech uses the smallest screw in the world over on the usb c port

[@adamklase8547]

Gotta love it more how OP doesn't even talk, touch or hint about it. He just throws a shot in of him unscrewing and carries on 🤣🤣 It's that vibe when you text someone 3 or 4 key points and they respond to the one you wanted the answer to least.. Jesus.. these YT ppl lol my god

[@rabumalal]

Thanks for video. Next time, it would be nice to consider disassembly of wheel.

[@IronMan-4C]

So why this mouse is sooooo heavy ? which part ?

[@HazewinDog]

based on where the weight is and the internal layout in this video, 100% the battery.

[@grgr7377]

@@HazewinDog is it possible to throw away the battery to make that mouse normal weight and work on the cable instead only? That mouse is ridiculously heavy. And its wheel is a joke btw.

[@haomingjin1617]

I just hope they don't put the screws behind the black stickers/feets. These are not very sticky so you probably will need a new set.

[@ats-3693]

Just carefully use a sharp knife point to feel for the screw holes then pierce a small hole in the rubber pads to put a screwdriver through, don't pull the pads off at all.

[@AndrewLinw]

thank you for the video

[@elysiumcore]

i barely used this mouse to a brand new computer.... the battery will not charge past 5% terrible especially for how much it cost

[@florianhofmann7553]

Does anybody have the dimensions of that little spring beneath the wheel? Is it maybe like 0.2*3*15 mm? Many thanks

[@RealKennethChoi]

is there a way to modify the mouse so that it produces a clicking sound

[@jmtornetta]

You can install Omicron switches which make a click noise. I did this yesterday because the default switches on the 3s are very cheap and began failing after 1.1 year (1 year warranty).

[@HazewinDog]

it should make a pronounced clicking sound...

[@bradloflin6776]

what is the battery specs for replacement? Mine is already dying.

[@peloponeso31]

i have recently bought this mouse, how much did the battery last to you?

[@nciso]

Mine is just dead... About 5 months :(

[@alzard6828]

2 years and working like new

[@HazewinDog]

almost 2 years of use here, only had to charge it a couple times despite using it both at home and at work. I suspect the battery to last as long as I could ever need it to... unfortunately my left click just stopped working properly, so I came here to see if the switches are user replaceable. Guess not...

[@gidonreuben-shemia2044]

@@HazewinDog same problem with the left click and that with such an expensive mouse

[@KhaosOfficialYT]

what kind of screw is that top one?

[@el80ne]

tiny hex screw

[@khakers2.099]

It's a T5 torx for anyone else looking

[@Podolski55]

Thanks!

[@vladimirfasyura8191]

Отлично... левая кнопка отдельно снимается

[@gabbi-sees]

My mouse hasn't been connecting to my computer via Bluetooth or even by cable. Anyone know if that's something that can be fixed with any of the internal parts?

[@cesarandres1288]

I have the same problem, I looked everywhere and it appears that it is a common problem for this model, didnt find any solutions, maybe is a ribbon that is a little bit loose, try opening it up and look for that

[@justz9435]

Of course they had to make 1 screw different

[@alanl3292]

kudos to logitech for not using clips but screws :)

[@zigsrig]

This mouse is complete garbage. Do not waste your $99 on it!

[@mikal_1]

My MX Master 3 sidebuttons has gone to shit after 8 months. And the dongle range must be VERY close to the mouse unless it stutters and lags. Fucking garbage mouse

[@el80ne]

fuck the dongle, far better to use bluetooth so it doesn't take up a usb slot assuming your computer has builtin bluetooth.

[@mattbak2466]

unplugging this battery is some cancer, worst shit ever

[@mattbak2466]

just impossible to unplug ,cant do it ;(

[@el80ne]

Use needlenose pliers. There's also a special tool used by motherboard builders that will grasp and slide it right off. But if you don't have that the nn pliers will work.

[@Frank_Pods]

A removable battery! Just like a PS3 controller!
