I don't know why some people are so against companies like Razer. There is nothing wrong with any of their products quality wise, yet people just have some negative disposition towards them because they are well-known.
I have a full on Razer setup, Blackshark headset, Blackwidow Ultimate 2013 Keyboard, Deathadder 2013 Mouse, and Vespula mouse mat. I have never had a single product of theirs have any malfunction or any problem whatsoever, which is one of the main reasons I like them; they are reliable. Yes, I've had gaming hardware from other companies, and sure it was all nice equipment, but Razer is really the top-of-the-line when it comes to gaming.
Sorry for the small rant, just wanted to give an educated opinion on Razer. Anyways, I would choose the Deathadder if I were you; it's got the perfect amount of buttons to set macros to and is one of, if not the most comfortable mice I have ever used.
