Excerpt: At the time of purchase (some 5 months ago), I had just started playing Guild Wars 2 (a massively multilayer online game) and I was looking for a gaming mouse to compliment just that type of video game. On that front, the Razer Naga delivered famously, leaving nothing much to desire further. Sadly, that was the extent of its significance, proving to be no more remarkable than some $30 gaming mouse when used for other sorts of games or applications.
Summary: I had another older Razer mouse that broke after about two years, but I really loved it, and bought this cheaper one as a replacement. It's not as nice as the other more expensive Razer I had previously, but it's still quite good. The only thing I'm not in love with is the height, placement and feel of the side buttons.
Summary: I am really enjoying this mouse. It is lighter than my older Logitech gaming mouse, and it took me a little to get use to it. They main mouse buttons are really sensitive and easy to use, very fast. I am mostly happy with the side buttons. I only use 3 of them as I tend to move the mouse reaching for the ones on the front side of the circle. The shape is very comfortable, mouse wheel is great. Happy buyer.
Summary: Synapse is a finicky program. Without it, the side buttons are nothing but replacement number row keys on your keyboard. When I first installed synapse everything was fine, macros were working and all that. After a restart my mouse wouldn't move, I'd have to uninstall synapse in order for it to function again. The mouse buttons were working, but it refused to move.
Pros: The mouse texture feels great. It doesn't attract dead skin cells or sweat at all. There was a problem on my older Naga Hex where I'd have to clean off the edge of the L/R clicks every few hours under heavy use.
Cons: Not sure if it's just my mouse but sometimes the right click doesn't actually click, this was happening right out of the box before any real usage and is still happening. It's essentially already clicked down. You can click with the same amount of force and you will get the click, but you won't feel it or hear it. Whenever this happens I have to rapidly right click to get it back to normal. This happens at least 2 times a day.
Summary: Great mouse for what I needed. The reason it is not a 5 star review is because the keybinds I assign to my buttons are often not activated upon restarting the computer or unplugging the mouse and using it on a different computer. I have tried saving out profiles, but I still frequently have to reassign those buttons binds and/or reopen the Razer Synapse software to get them to activate.
