GM4.0 GM8.0 Micro Switch 60M 80MLife Gaming Mouse Micro Switch 3 Pin Black Mice Left Right Button GM 4.0 8.0 (Red 4pcs GM4.0)

I have two Logitech G604 mice that I absolutely love. I've used them for about 4 years now at work and at home. They were about $80 when I bought them, so I definitely didn't want to have to replace them when they suddenly started having click bouncing problems. I do a lot of soldering work at my job and figured it would be a pretty simple job (your mileage may vary). I replaced the switches in one and decided to compare them side-by-side. The G604 uses Japanese Omrons, but there is quite a bit of travel in the buttons before it actuates. The Kailh switches seem to actuate the very instant you apply force to them. They definitely feel premium. They are no more or less noisy than the Omrons and feel like they have close to the same actuation force.Overall, I'm happy with the purchase. It saved me lots of money on replacing my old mice, and they feel great!

Had a G700 which I used the grey ones on, had a louder click than I expected but it was such a weird design (the G700) to get to the switches and de solder that when something else messed up I just tossed it in the garbage. I pulled out my old G602 (shelved due to the double click issue) and opened it up, much easier to get to switches! I used the red ones and I am very pleased with the choice. The mouse is like new now and has subtle clicks. Nice that I will be able to keep this around for a lot longer now.

They really do be clicking.I offered the GM red 4.0I have large heavy hands and fingers and these have some resistance so you get a lot of tactile feedback which I love about these.Soldered in well and fixed my mouse’s double clicking. (Picture provided.I installed these into a Logitech G604, which they don’t make anymore and are hard to get.All in all, they seem decent quality and work after soldering.

For those who are buying these switches for the Logitech MX Master 3S, my mouse had 2-prong switches. But you can use them still: just cut off the NC pin. And they are louder than the original ones. I gave them 5 stars because they are working fine, and nobody promised me that they would be quiet. We'll see how long they last.

Easy install into hot-swappable plugs, super satisfying click that is relatively high pitches without being grating. Responsiveness seems better, as the click feels crisper than the stock switches for this mouse. Even bigger bonus that you get more than two, saving you from having to purchase twice, not that they're overpriced in the slightest. Highly recommended, would buy again 100%.

Switches work great! I had a problem with my left click getting sticky shortly after soldering them into a 502 Lightspeed. Taking the mouse apart again, with its seemingly endless amount of screws showed that the flux I had used crept its way into the switch gumming up the works. I flushed the switch with a Q-Tip dripping wet with 90% Iso. That fixed the issue and its back to healthy working order.The G502 lightspeed is known for its Double-clicking switches. These will get you fixed if you're not wanting to spend the 100+ on a replacement mouse. Worth the effort, keep track of your screw location. Some screws are quite hidden, don't force anything, be thorough.

These function great, for a good price, only issue is that they each are tuned a little differently enough for there to be an audible difference in click.Kind of annoying, but as long as you check the noise they make beforehand and match them up, you should be fine

These switches are definitely tougher to press than the stock Omron switches. It's no a problem for use in productivity work, but for those who are using this for gaming, you might want to look for something a little softer. On the trackpad it's nice to have tougher buttons so you don't make accidental clicks as you usually place the whole weight of your palms on the unit.I chose the GM8 for it's claim in longevity, and we'll see if these buttons last longer than the 3 years that the stock Omron switches lasted. Well, now I have 2 spare ones to use even if these are shorter lived. Let's hope I don't have to keep opening my trackball.
