They quickly developed the double click, and there doesn't appear to be any way to fix it, except buy a new one.
Yup. Buy new, actual quality microswitches like japanese Omron D2F-01F, Kailh GM 8.0 or Kailh GM 4.0 for about 1-2 USD/piece, and solder them in after you desoldered whatever crap Razer put in it on the assembly line. For 5 USD tops, you have a better mouse than it ever was, and it will stay that way for a
considerably longer time. Years. : D
The new opticals will probably last longer than the previous switches used by Razer, even by their nature, but if they fail, there are already replacement options on the market, albeit not too many as of yet (as you can't put mechanical switches to mice that use optical ones by default, so the technology needs more time to be more widely used to have more options on the aftermarket).
The same bs goes rampant even at Logitech with their Omron D2FC-F-K(50M) switches. They feel pretty nice and all, but in terms of durability, they are absolutely low tier. My G PRO Wireless had clicking issues in 7 months. We are talking about an overengineered, 150 USD mouse with a literal "
endoskeleton" (high-end hardware, layers of parts, 31+ screws, basically perfect build quality), and it's still not an uncommon spectacle, it's a known issue, while it still couldn't rock a japanese Alps encoder for the wheel. Again, we are talking about a ~1-1,2 USD part. And this price is for the end user for a piece, not the price for a huge company which buys these things in the hundred thousands/millions...
If I had paid money for the Logi, I would have been seriously pissed, but wouldn't have hesitated to go ahead and change the switches out (and the encoder if I'm already at it) anyway, as I'm not gonna bother with warranty with this kind of problem; you wait for weeks, and in the best case scenario, they'll put the same
<Mod Edit> in it again.
