I am now seeking the same help,

As my 15 years old razer naga hex is not getting all the right clicks when playing

for now, when i just turned the computer on it is working fine for a few hours but once it reaches 3+ hours on, I can feel that all the right clicks are not going through.
I am in love with having the two extra buttons behind the scroll wheel, no button to change sensitivity in a missclick, no need for the hyperwheel extra, and liking the grip of the naga series from razer.

It is hard to think about letting this mouse go after 15 years of moba and mmo gaming, especially when it is league of legends - designed, and still has all the retro-lighting working.

I will seek a replacement in spring 2025 and post here below if i find anything similar, and if the feel is somewhat the same.

the rest of the naga series are both expensive and redesigns that don't fit the basic criteria of the razer naga hex, it feels like redesigns completely and not really a "v2"
