-maintain Well in hand, ergonomic, no problem to reach the buttons (just a hand to take)
-Fluide Says, no lags, perfectly functional
-The Supplied software and setup are almost perfect, we could just allow you to switch between more than two profiles at a time (to load a third, open a file)
The downside:
When setting on a game, you can not match a command to a button. This is actually the mouse button that is setting a key on the keyboard. This is the only thing damage.
Otherwise, it is really perfect. For that price, just feel free. You can create as many profiles as you like, but pressing profile change button, you can switch between two pre-set profiles. To switch on a third, fourth, etc., you must go to the mouse software and load the file that corresponds to the desired profile. Doing so also gaffe for buttons: one button does not correspond to a direct control on a game: you have to put your order on a keyboard key and then set the mouse so that it corresponds to that key. I do not know if I am clear but here :)
