The Roccat Lua suits me perfectly. I was looking for a simple mouse to play mainly in FPS and TPS and being an old school player, I have no need of side buttons (wrongly?).
The Roccat Lua 25 is very well finished, (better than Razer!) The very smooth plastic top is nice, as for him on the sides, granular, has good grip and greatly moderates perspiration and deposits. Very nice in hand.
As someone who holds his mouse fingertips, size fits me perfectly. By cons, for those looking for a model on which the palm of the hand (MMO players?) Lua will be banned.
Very pleasant feeling of gliding, click and double click also. One downside to the very sensitive right-click (certainly a habit).
The wheel (adjustable scrolling through the driver) is neither too hard nor too soft (with a leaning towards the "hard"). Big asset, it locks firmly, which is a plus in FPS (NIOHC weapons)
I love the look, one can choose to light via the driver, to flash on or off the logo.
And indeed the driver is very good, very easy to use. No complaints (download from the website of Roccat).
In conclusion, certainly one of the best profit playful mouse in this price range. I prefer not commensurate to my old Razer.
For seeking precision (DPI setting on the fly via a button located but accessible medium) LUA filled his office perfectly.
This is the build quality is most impressive (no play, plastic quality) and very nice overall feel.
Basically it seems to have a mouse to 50-60.
Only the absence of side buttons can put off some. For those who care, go for it!
PS: this time no returns on reliability, so I think I will add a comment within a year.
