The DarkGlider from Sharkoon fit my hand well and it took really no time at all to get used to slinging it around on my desk. The weighting system with multiple sized weights help you to fine tune the mouse to your liking, just like I found it to feel best with two 3.1g weight and a pair of 3.7g weights. The DarkGlider has a good contoured feel when on the table, but it does lead to one issue that branches into two things. The mouse is so rounded and the contours on the side aren't deep enough to allow you to pick up the mouse and reposition it very well, especially in the heat of battle. I really had to force my grip to lift it and it usually didn't end well because of the high lift distance preset to the mouse. So if the lift is awkward, you crosshairs are moving too much to be accurate any more, there is always a bit of "rebound time" where you had to resituate the mouse.
As long as you leave the mouse on the table or on one of the included mats, with a high enough DPI setting, you really don't have to lift the mouse all that much, but for low DPI snipers, be aware of this when tracking your pray on who is on the move.
The software side of things is very intuitive and pretty simple to navigate. The programmability of the buttons over the five profiles should take care of anything almost by default and if the presets don't cover your needs, set up a Macro to fill the gap. I also like mice with a visible DPI setting, that way I don't have to click around with buttons to see I was where I wanted to be, it just seemed wrong at that moment in the game. If it weren't for the LD issue, there really isn't anything I can complain about with the Dark Glider and when accompanied by the DarkGlider Gaming Mat, I really did enjoy gaming with it.
For those on this side of the pond, if you like what you seen and read about the Sharkoon, I suggest you get with a forum buddy and see if he can ship one over. Like I mentioned before, I don't know that there are any plans to sell them here, at least not right now. For those with local listings of the Sharkoon DarkGlider, if you have a large mouse mat or prefer to gamer at high DPI levels, the DarkGlider is worth a look. If you tend to prefer lower DPI levels and are thinking of a mat like the 1337 or DarkGlider mat, the lift distance and awkward way to lift it might be a deal breaker for you.
With a listing price of 39.99 Euros or right around $50, this is a well equipped solution that gives you everything most users desire.
