Excerpt: The Razer Lachesis gaming mouse originally launched in 2007, with a dramatically curved, ambidextrous design and a 4,000dpi sensor. Three years later, Razer has released a new Lachesis, which is not so much a sequel as a refinement of the original. The most important change in Lachesis 2.0 is the 5,600dpi sensor, which puts it on par with other top-end gaming mice.
Pros: Excellent, ergonomic build for people with larger hands; great sensor; ambidextrous design.
Cons: Only two side buttons are really accessible; not great for people with small hands.
Conclusion: In this section I am going to write a brief five point summary on the following categories; Performance, Appearance, Construction, Functionality and Value. These views are my own and help me to give the Lachesis 5600 gaming mouse a rating out of 10, a high score does not necessarily mean that it is better than a similar mouse which has been reviewed by another writer here at Benchmark Reviews, which may have got a lower score.
Pros: High sensitivity 5600 dpi 3.5G laser sensor, Customisable RGB LED's in scroll wheel and logo, Nine fully customisable buttons, 60kb onboard memory for macros, profiles and configurations, Adjust sensitivity on the fly (with OSD), Great construction, Ambidextrous, Great all round mouse
Cons: Color options are very basic, more settings please, Side buttons can take some getting used to, Price is competitive but still quite high, Some colors won't display on logo
