Summary: I'm an IT guy, sys admin type, and I destroy mice. Cheap mice wear out. I replaced a Logitech G5 gaming mouse with this one, and I was pleasantly surprised with how well it works, how good it feels, and it is showing no signs of giving up the ghost. Pleased with the product.
Summary: I don't play very many PC games, so I don't need a mouse with a ton of extra buttons. However, when I do play PC games, this mouse is a great purchase. The fiber cord doesn't tangle, the sensitivity is adjustable through the two buttons above the wheel, and it is very comfortable to use.
Summary: I would not play CS GO with out it smooth accurate, handles well with my hand, very reliable and really takes a bashing in a game, those double sensors Rock, you get a laser and an infrared, it can tackle all situations. this thing was built for FPS games, especially with the sensitivity control and adjustable & customizable side buttons.
Summary: I picked up the Imperator after returning the Mamba. Unfortunately, the Mamba was a bit too big for my hands and reaching the thumb buttons was a bit of a strain. After researching Razer products more, I chose the Imperator specifically for the ergonomics and the adjustable thumb buttons. I can say that this is one of the most comfortable mice I've ever used.
