eeeeeeeeeeeeeeehhhhh???? even with my bass on max and volume to the top and the subwoofer sitting on a plank under the desk (aka: right under the desk) with a Roccat Tyon and a Roccat Alumic (or Taito) i have zero (yep 0 ) issue of the sort...
i had countless LED optical and laser optical mice, LED optical where the most uncomfortable except for the Logitech G602
for the moment i never used above 2600 dpi (G600/G602/GXT166/Tyon) the GXT was the funnier ... 16400 dpi but LED (see the Post scriptum aht the end of my post)? does that even exist? i looked the sensor and the illumination device was totally not a laser but a red led just like in my old intelimouse i had in the past.
ofc ... if you take a p.o.s brand like Razer or Madcatz (the 2 brand with the most RMA in all my hardware and peripheral i got for my rig... and also the 2 brand with the most "fried sensor" i had)
they are better one out there... and a lot ... (not hard to do better than Madcatz ...) the only good thing about the R.A.T.Z is the shape customization.
altho even adjusted for me my R.A.T. 7 still feel like a p.o.s and less comfortable, compared to my Tyon (and got a sensor fried ...)
what i love with the Tyon is the button placement, i loved the Naga idea but not Razer ... so when Logitech did the G600 i was quite happy to switch, then the G602 then the Trust GXT166 (which even for a low cost mouse lasted way longer and was way better than a Naga, for half the price ... ) but the Tyon buttons placement is on a whole other level ... not all under the thumb it's a bit less tiring (yep ... thumbpad was tiring for me mostly due to the 6 button that were situated on the back part) totally intuitive once you remember the numbering, and very ergonomic. the only thing i did not get used is the fin switch but ... if i set a emergency shortcut on it ... i use it naturaly ahah ie: medkit, glider, eject, close all windows
PS: all mouse are optical just the illumination device change ... (LED or laser)
(well the one in the video is TKL FX so i wonder about it 
)
