Viper 8khz left click constantly stops working, brand new.

Good afternoon, 

 

I purchased the viper 8k ambidextrous mouse and it arrived two days ago, since then the left click has completely stopped working, probably at least 10 times by now. Having to unplug the mouse and back in again to get it working or use a different mouse to be able to go through options.

Things I have tried.

Tried multiple different USB ports on the computer

Uninstalled and reinstalled the firmware

Uninstalled  Synapse and reinstalled it


Tried using the mouse with and without Synapse being open.

Tested my other mice to make sure it wasn’t a USB port issue, they worked fine. 

 

I have gone through the forum and it seems those are the main “fixes” that have been given to test so I have gone through them and it’s still happening. It is a shame as I’ve never gone with razer before and saw I could finally get a mouse for left handed side buttons which are seemingly rare nowadays. 

If there is a fix for it I haven’t yet tried I will happily give it a go. The mouse does seem quite comfortable and when it works for the few minutes before disconnecting it seems okay but not if it plans to break after few minutes.

 

Thanks

Hi polyCamelheaven931, 

 

We’re sad to know that the newl bought Razer mouse’s left click completely stopped working. Thank you for sharing the steps you tried. You mentioned that using another mouse on the same computer works. Have you tried connecting the Razer Viper 8KHz to another working computer? This is just to properly isolate the issue. Regardless, please PM me your Razer mouse’s SN: (Follow steps here: https://mysupport.razer.com/app/answers/detail/a_id/548/~/how-to-find-the-serial%2C-product%2C-or-part-number-on-a-razer-device) and link of your receipt in a PDF format: (Save the shareable files via any online drive account listed here: https://mysupport.razer.com/app/answers/detail/a_id/4011?_ga=2.197232171.544708261.1744067200-1885068520.1744067200&_gl=1*vo487o*_ga_3TRK53PM75*MTc0NDA2NzE5OS4xLjEuMTc0NDA2NzM0My4yNC4wLjA).

I have the exact same problem, and I've tried everything to fix it, but nothing works. The right click only works intermittently. It's truly awful. How is it possible that a $1 mouse works perfectly with both the left and right clicks, while a $70 mouse doesn't? It's really sad...

I returned it for a refund. The staff above refused to message me in 9 days which is awful for a company. If you have the same issues I’d recommend just getting your money back, seems they have no intention of helping.

I appear to be having similar, if not the same issues. Just purchased as well. It worked for a single session of about an hour, though felt unreliable from the get go. Now Left/Right click buttons just stop working permanently. Followed basic troubleshooting. doesn’t work still, it’s not even a hz change issue. Someone, elsewhere, brought up using a blackwidow v4 - you wouldn’t have it by chance? Maybe these two conflict with one another?

My Razer Viper 8khz didn’t do that in the beginning but started doing it only recently. On windows the ctrl-alt-del and escape fixes it temporarily.  So is it something that the Synapse is writing on the onboard memory? Also the left click doesn’t work at all on Linux even after setting the poll rate to 125hz.

Ok now the left button works partially under linux mint but can’t drag windows or open the start menu.

How is it possible that no one from Razer support is taking responsibility for their product, knowing that many people have the same problem?

    Same problem, it's really annoying.
