Not at all. That's caused by not using the switch's NC contact for debouncing. Either incompetence or planned obsolescence on the part of the people laying out the PCB and writing firmware. More info here: https://www.overclock.net/forum/375-...ncing-mod.html

Interesting. To be honest I never had this issue. In my cases it was always just switch fault.

So why some people have this issue some not? Some after few days or months and others do not at all.


I was thinking about this mouse but with this price it just make me worried.

If an engine is designed to last 200k miles when used with oil, and the car manufacturer decided not to put oil in it, you don't blame the engine when it fails after 20 miles. It's silly to compare engines based on how far they can go without oil, and it's just as silly to blame this type of failure on a SPDT switch.

Snap action switches are inherently bouncy. If you're only looking at the normally open contact, you know for sure the button is pressed if it reads closed, but if it reads open you don't know if the switch got released, or if the contact is bouncing. Most mice use a delay or timeout, the shorter you set the delay, the faster the switches wear out(there are other things that can change how fast stuff wears out, like humidity and abrasive dust). The correct way to debounce switches is to use the second switch contact. When the normally closed contact is closed you know for sure that the switch is not pressed. So you just latch on whatever contact read "closed", and you get extremely reliable delay-free debouncing. The cost to do this when designing a mouse is one capacitor per switch, or one additional pin on the microcontroller per switch. The capacitor option would cost less than half a cent per mouse. The extra pin option in many cases is free.

I'm not native english so it's a little hard to understand it exactly

So it would need to change something on pcb or/and add forth pin for switch? I'm not sure if I understand what you wanna say.

Anyway... it's the problem of g pro wireless or all mouses? But why then it happens for some people faster and some not? I'm confused.

Most mice. There are a handful that might do it properly, but I haven't confirmed it. Having extremely low latency is one indication, but that's not definitive. I'd say look at the ~25 best mice in the click latency thread, and search reviews of those models for anyone with a double clicking problem: https://www.overclock.net/forum/375-...-compiled.html There are a couple Bloody brand mice that seem to advertise this.

As for why some switches wear out faster than others, in the same model mouse, that's probably environment and amount of use. If you're comparing different mice, a more reliable model likely has much more delay in the firmware.

To fix this temporarily, you can just replace the switches or clean the contacts. To fix it properly you would need to rewire the switch to use the third pin that the switch already has.

The first image is what's happening inside a mouse that gets the double click issue(pull up resistor is generally inside the microcontroller). The second and third are how the switches should be wired from the factory. The mod in the other thread uses an extra IC in order to overcome the pull up resistor built in to the microcontroller.

I have bad luck with the GPW so far. I got 4 copies all of which double clicked on me upon the first day of use. The static electricity theory might be true to an extent when the mouse starts double clicking, but eventually gets worse to the point where blowing into the charging port/mouse crevices becomes ineffective at stopping the issue.

Weird enough, the double click issues also affect my g305. However, it takes much longer for it to develop vs the GPW. The only Logitech mouse I have that never double clicked for me so far would be the g900. Perhaps this is a design flaw with the newer Logitech mice?

Any of you folks have another way to stop the double click issues?

Has anybody done a click latency-comparison between the GPW in wired and wireless mode? It would be super interesting to see if there's any discernable difference between the two!

I have had my newest replacement G Pro Wireless for about a week now. It's an 1844 batch for anyone interested. I've had a few before this - an 1827 (I think) that double-clicked like crazy out of the box. Exchanged for a 1912 batch that had zero double-clicking issues (yay!) but the wheel was sometimes sticky (ugh!). Finally, exchanged for the one I have now. So far, so good with this one - no double-clicks, no dropped clicks, good wheel. Here's hoping this holds up...such a nice mouse but it's a bit of a gamble at times. :/

Bought a Logitech G Pro wired, with Hero sensor. Welcome me to the club, LoL.

Love the shape (the sides could be a bit more flat though). Love the weight. Love how small it is. Can't speak on sensor performance. The buttons are fantastic.

The skates are utter trash though. Feels extremely scratchy. Should I purchase new skates (Hyperglides or Hotline!) or a new mat? My Hiro is like four years old, though my old mouse glides absolutely fine on it.
