I had an avior for a short time (basically got it for free from best buy but returned it for a da chroma). the sensor performs very well when you update the firmware to v3.38. it has a nicer coating than zowie's imo and clicks are lighter, which you may prefer. havent heard about lifetime/failure issues with mionix so i assume that means they are ok. one funny issue i had with mine was that when I tried to change the lights on the mouse (one light for scroll wheel and one on the logo) they would always be different colors unless I chose red. so if i wanted both colors to be blue, one would be blue the other would be orange or something. i ended up just turning off the lights like i do w mice that allow it though.

i heard fk1 got massive buttons lags, is that the case for ya ? :)

No. 3-5 ms delay compared to my Steelseries Xai

I had one (it's in Kuwait now), it's noticeably laggier than logitech mice disregarding click stiffness, like at least 10ms, also if you want me to give you a list of mice I've tested and how I've felt their lag then I can post it.

I would definitely go with the Ninox Aurora if I were you. Have you tried it out? You must. I don't know anyone who hasn't fallen in love with it's sublime shape, solid build, and heavenly sensor. If I could take just one item with me to a desert island, it would be a Ninox Aurora.

If it's the perfect mouse for you, why do you want another?

If you want to experiment around, buy whatever you feel like buying - but don't sell the FK1.
