I definitely recommend buying, I didn't notice any disadvantages.
In general, the product is pleasant, suitable for every day. The charge holds decently.
If you are not alien to the Deathadder line - take it!
Pros
Ergonomics. Design. Style. The quality of materials.
Positioning is accurate.
Cons
By timeout, the sensor falls asleep, this is normal. But when he wakes up, Synapse does not see the mouse. And the backlight doesn't work. Well, at least DPI does not fly off .
Treatment: unload Synapse, run again. This is not a solution, but a temporary move.
: something has been ated in the software, now there is no glitch when the mouse is not detected after hibernation.
