I've used a Razer Naga Epic for more than 8 months at my job. Having useful keys, like enter, spacebar, ESC, f5, and arrow keys on my mouse has been a dream for years, and the programmable 12-pad makes this a reality. The Synapse service was designed for someone like me, who uses the same mouse at home and work, even though I don't use it. Synapse syncs mouse configuration settings across different computers, installs, etc. This way, you don't lose your sensitivity and custom keybinds and macros. However, being required to use Synapse is madness. The Naga Epic has "offline" drivers. With Synapse, I wouldn't be able to use the mouse at work because of (realistically) strict IT security standards. It's a shame, since I really enjoy my Razer mouse, and was going to start supporting them.
