If you are coming from the 3.5g, the 2013 deathadder IS LIGHTER. yes that's right, so if you play fps games, you are going be overshooting for a couple week if you have been using your old deathadder for a long time. Other than that, all the other reviews are pretty accurate. Yeah having synapse running in order for the configurations to work but that really isn't a huge deal. synapse doesn't take that much of a load on your ram. Does synapse so it's job in properly configuring your mouse? Yes. I frequently play from my laptop to my desktop and having the features and profiles transfer over whenever I play them is nice. Now as to why your mouse settings are saved onto a cloud and rather than the mouse itself, I have no idea and doesn't quite make sense. But if you are going to review a product, you review it for what it has, and not what it doesn't have.It's a great working mouse with synapse that get's the job done (at least for me it does).
