$50 / £50
However, it can often be found on sale for $30 / £35
Shape
Weight - 96g
Dimensions - Length - 127mm Width - 61.7mm Height - 42.7mm
The mouse has a right handed shape.
Hand size - 17cm x 8.5cm
Palm - Very comfy, large ergonomic shape is good.
Claw - Not for small hands, for my hands it was usable.
Fingertip - You will need larger hands.

Feet - Terrible, inconsistent, felt like sandpaper.
Cable - Braided and very stiff, also terrible.
Sensor
Razer's own sensor
DPI of up to 6,400
Lift off distance - 8 playing cards
The high lift off distance and high weight lead to a lot of cursor jiggle and small jitters.
Buttons
The primary mouse buttons were fine and on par with other mice in this price range.
Here is a link to a sound test of the buttons.
Side buttons - Weren't too bad, they are big and don't take a lot of force to use.
Scroll wheel - Not very good feel, found I double scrolled a lot and it rattled a bit.
Lighting/Software
The lighting is present on the scroll wheel and logo however, it is only green, the lighting effect such as strobing can be changed in the Razer software.
Software was good but not much can be done to the mouse using it. You also need the software, which requires making an account.

Verdict
Overall this mouse is very disappointing, at $50 it is an absolute joke and on sale it is better but still a hard sell. It is definitely a stripped down version of a Deathadder, but not worth the price. I wouldn't recommend buying this mouse.
Buy the Razer Deathadder Essential
