Look here

It has been reported over a year ago ..still no fix and not even sure that Razer acknowledge that there is a problem.

Yeah I even commented on that post…. *Sigh* Guess my ccry for help is falling on deaff ears?

So att this point even Razor themselves won’t even bother helping? Figures as much. Succh a scummy company! Looks like I’ll be buying anytthing BUT Razor produccts ffrom now on sadly. Tthanks for the heads up at least. Sad it took this long for soomeone to commentt.

Well i don’t own it .. i was looking to buy it and read in reviews about this issue so i came to the forums to see … well this keyboard would check every box for me but i will not play roulette because of this issue

Same issue here, with the same model. No change to polling rate reduction or hypershift mode, or, hilariously, closing Synapse, make any difference - nor should  disabling features you paid for be a valid ‘fix’. The lack of patch or firmware to fix this issue and Razer’s inability or unwillingness to recognize a serious system problem with a product, effectively gaslighting their clientele, means no more Razer purchases for me, in perpetuity.

I’ve been having the exact same issues for the few months ive had this keyboard. I was able to temporarily fix the issue by buying different switches, but has been doulbe typing only a month in with the switches. for the love of god, i shouldnt and no one else should HAVE TO buy new switches. I cannot tell you how many posts, subreddits, threads, etc i have seen about people having this issue and not one of them has razer helped or been a part of in the discussion. Razer is just a novelty brand. They have nothing of value to offer compared to their competitors. This would be the last razer product I buy which is disappointing. I loved their previous keyboards, mice etc but their quality control is next to non-existent if this many people are having the same issues with their products. And I mean for the love of god, Razer could at least be on this shit and troubleshooting or in the least sending mfs another damn keyboard. I think what it was, is that they are trying to get rid of the faulty products to customers. Most customers won’t try to return it or use their warranty out of inconvenience and most likely buy another one or just move on. You’re absolutely right that razer is scummy, and none of you lot should get them another penny of your money.

The only solution seems to be using this keyboard chatter program from softpedia. Make sure you click the correct download button.

The software does exactly what you would think..if your keyboard sends the same key within a certain time frame the additonal key presses are erased. I have my threshold set to 125ms and that has fixed the issue. Kinda sad we have to use something like this. 

So I downloaded this and am now using it. Weather or not this works and is gonna be my long term fix, IDK as of yet. But thank you for this. And yes it is sad we have to rely on a 3rd party to fix something Razer themselves refuse to fix or even acknowledge! This is totally scummy IMO. But it’s what we get for letting this company get too big, abuse it’s customers, and get away with certain things.

So. This was an issue I had before. I bought this keyboard last October. I had the issue after a couple of months. I stopped using it, then I started using it again before summer, I the whole keyboard with FOUR completely difference switch (different brands, actuation weight, tactile/non-tactile) and I still reported issues after about a week or two. So it seems no matter what is done, the double-clicking comes back. Even after extensive testing right after swapping the switches.

Now, after many months I am testing the keyboard again as I have seen there have been a lot more threads about the matter and some firmware updates. So as of recent, Razer has finally addressed this, they stated that is has something to do with their Orange switches*. Initially, myself and others, have concluded that it may be a faulty board. That left us with almost nothing we could do. After researching a bit and seeing that they have dropped some firmware updates, I am testing again to see if there is a fix as I saw some recent posts saying they no longer are having any issues randomly.

I am going to be testing it for a bit, I just updated mine to type this us. Wish me luck. I am sure it'll start double clicking (main the S key for me, there are some other ones but S always starts acting up first) soon. I really like this keyboard. I have vowed to stop purchasing any Razer brands after the quality control on the DeathAdders went to shit and this keyboard was the final straw. All American BIG corporate brands are going down the drain with quality control. This is unacceptable. Even if it was a firmware bug it is still unacceptable being such a main-line keyboard and for this to have gone for so long at this scale.
