Turning Logitech G305 from abysmal to great
When I bought a shiny Logitech G305 a couple of weeks ago initially everything was going great but I quickly discovered that I keep accidently pressing the right mouse button because I tend to rest my hand on the mouse with quite a lot of force when pressing the left mouse button. Apparently it takes infinitesimally little force to press the main buttons on this mouse. I tried getting accustomed to using it but after a month of usage I discovered that it just keeps happening and that using this mouse is just annoying.
The only reason why I am writing this is to document this problem as I heard nothing about this before buying the thing. I have a hard time believing that I am the only one struggling with this. How come nobody decided to loudly and publicly complain about this on the internet before? Complaining about things is literally what the thing is for.
Why is this a problem? Who is in the wrong? Is it me because of my large hands and my brain being conditioned to misuse the mouse by 15 years of using a cheap A4Tech X710? Is it the entire Logitech design team the entirety of which should be immediately fired? We can only guess but fortunately if you have the same problem then you can try to fix the mouse instead of contributing to the global ecological catastrophe by buying a new one.
The easiest fix for this is to simply buy a new pair of switches which require a higher actuation force to... actuate. I know nothing about mouse switches but I heard the name "Huano Blue Shell Pink Dot" before so I bought a pack of those on Aliexpress after looking at some actuation force stats. The good news is that after replacing them the mouse feels great to use and the problem went away completely.
Below you can find the the disassembly pictures which hopefully will make performing this replacement possible for everyone. If you just want to replace the main button switches like I did then you can jump right to "Accessing the main button switches" after performing the initial seven steps.
Disassembly
- Turn off the mouse by flipping the switch at the bottom so that the red color is visible.
- Open the battery cover and put it aside.
- Remove the battery.
- Remove the four sliders from the bottom of the mouse.
- Remove the four screws which are hidden underneath the four sliders.
- Gently lift the upper part of the mouse out of the bottom shell minding the two connectors.
- Disconnect the two connectors gently so that you can separate the two halves of the mouse.
Accessing the side button switches
- Gently disconnect the connector linking the side button board to the main board.
- Remove a single screw holding the side button board.
- Gently lift the side button board up.
Accessing the mouse wheel encoder and switch as well as the DPI selector switch
- Remove the four screws which hold the board down.
- Gently lift the board out of the plastic shell.
Accessing the main button switches
- Remove the three screws which attach the battery compartment to the upper half of the shell.
- Gently lift the battery compartment out of the shell minding the power connector and the main switch connectors. Note how the DPI LED "light channel" made out of semi-transparent plastic sits in the battery compartment housing.
- Remove the four screws holding the main buttons and gently slide them out of the upper part of the plastic shell.
- Remove the two screws which hold the two plastic springs located below the main buttons.
- Take out the two plastic springs located below the main buttons.
- Remove the four screws holding the two main button switches.
- Gently wiggle out and then slide out the two main button switches. I did this without detaching the main button cables from the upper part of the plastic shell to make sure that they cables don't get damaged.
In case you mixed the screws up
- four tiny screws with small heads hold down the two boards on which the main button switches are located
- four large screws are located below the silders
- all other screws with large heads are identical
